# SYNOPSIS
#
# AX_PREFIX_CONFIG_H [(OUTPUT-HEADER [,PREFIX [,ORIG-HEADER]])]
#
# DESCRIPTION
#
# Generate an installable config.h.
#
# A package should not normally install its config.h as a system header,
# but if it must, this macro can be used to avoid namespace pollution by
# making a copy of config.h with a prefix added to all the macro names.
#
# Each "#define SOMEDEF" line of the configuration header has the given
# prefix added, in the same case as the first character of the macro name.
#
# Defaults:
#
# OUTPUT-HEADER = $PACKAGE-config.h
# PREFIX = $PACKAGE
# ORIG-HEADER, from AM_CONFIG_HEADER(config.h)
#
# Your configure.ac script should contain both macros in this order.
#
# Example:
#
# AC_INIT(config.h.in) # config.h.in as created by "autoheader"
# AM_INIT_AUTOMAKE(testpkg, 0.1.1) # makes #undef VERSION and PACKAGE
# AM_CONFIG_HEADER(config.h) # prep config.h from config.h.in
# AX_PREFIX_CONFIG_H(mylib/_config.h) # prep mylib/_config.h from it..
# AC_MEMORY_H # makes "#undef NEED_MEMORY_H"
# AC_C_CONST_H # makes "#undef const"
# AC_OUTPUT(Makefile) # creates the "config.h" now
# # and also mylib/_config.h
#
# If the argument to AX_PREFIX_CONFIG_H would have been omitted then the
# default output file would have been called simply "testpkg-config.h",
# but even under the name "mylib/_config.h" it contains prefix-defines
# like
#
# #ifndef TESTPKG_VERSION
# #define TESTPKG_VERSION "0.1.1"
# #endif
# #ifndef TESTPKG_NEED_MEMORY_H
# #define TESTPKG_NEED_MEMORY_H 1
# #endif
# #ifndef _testpkg_const
# #define _testpkg_const _const
# #endif
#
# and this "mylib/_config.h" can be installed along with other header
# files, which is most convenient when creating a shared library (that has
# some headers) whose functionality depends on features detected at
# compile-time. No need to invent some "mylib-confdefs.h.in" manually.
#
# Note that some AC_DEFINEs that end up in the config.h file are actually
# self-referential - e.g. AC_C_INLINE, AC_C_CONST, and the AC_TYPE_OFF_T
# say that they "will define inline|const|off_t if the system does not do
# it by itself". You might want to clean up about these - consider an
# extra mylib/conf.h that reads something like:
#
# #include <mylib/_config.h>
# #ifndef _testpkg_const
# #define _testpkg_const const
# #endif
#
# and then start using _testpkg_const in the header files. That is also a
# good thing to differentiate whether some library-user has starting to
# take up with a different compiler, so perhaps it could read something
# like this:
#
# #ifdef _MSC_VER
# #include <mylib/_msvc.h>
# #else
# #include <mylib/_config.h>
# #endif
# #ifndef _testpkg_const
# #define _testpkg_const const
# #endif

# DESCRIPTION
#
# This macro retrieves the compiler version and returns it in the cache
# variable $ax_cv_c_compiler_version for C and $ax_cv_cxx_compiler_version
# for C++.
#
# Version is returned as epoch:major.minor.patchversion
#
# Epoch is used in order to have an increasing version number in case of
# marketing change.
#
# Epoch use: * borland compiler use chronologically 0turboc for turboc
# era,
#
# 1borlanc BORLANDC++ before 5, 2cppbuilder for cppbuilder era,
# 3borlancpp for return of BORLANDC++ (after version 5.5),
# 4cppbuilder for cppbuilder with year version,
# and 5xe for XE era.
#
# An empty string is returned otherwise.

# SYNOPSIS
#
# AX_COMPILER_VENDOR
#
# DESCRIPTION
#
# Determine the vendor of the C, C++ or Fortran compiler. The vendor is
# returned in the cache variable $ax_cv_c_compiler_vendor for C,
# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for
# (modern) Fortran. The value is one of "intel", "ibm", "pathscale",
# "clang" (LLVM), "cray", "fujitsu", "sdcc", "sx", "portland" (PGI), "gnu"
# (GCC), "sun" (Oracle Developer Studio), "hp", "dec", "borland",
# "comeau", "kai", "lcc", "sgi", "microsoft", "metrowerks", "watcom",
# "tcc" (Tiny CC) or "unknown" (if the compiler cannot be determined).
#
# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT
# with an appropriate preprocessor-enabled extension. For example:
#
# AC_LANG_PUSH([Fortran])
# AC_PROG_FC
# AC_FC_PP_SRCEXT([F])
# AX_COMPILER_VENDOR
# AC_LANG_POP([Fortran])

dnl @summary figure out how to build C programs using POSIX threads
dnl
dnl This macro figures out how to build C programs using POSIX threads.
dnl It sets the PTHREAD_LIBS output variable to the threads library and
dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
dnl C compiler flags that are needed. (The user can also force certain
dnl compiler flags/libs to be tested by setting these environment
dnl variables.)
dnl
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
dnl multi-threaded programs (defaults to the value of CC otherwise).
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
dnl
dnl NOTE: You are assumed to not only compile your program with these
dnl flags, but also link it with them as well. e.g. you should link
dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
dnl $LIBS
dnl
dnl If you are only building threads programs, you may wish to use
dnl these variables in your default LIBS, CFLAGS, and CC:
dnl
dnl LIBS="$PTHREAD_LIBS $LIBS"
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
dnl CC="$PTHREAD_CC"
dnl
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
dnl default action will define HAVE_PTHREAD.
dnl
dnl Please let the authors know if this macro fails on any platform, or
dnl if you have any other suggestions or comments. This macro was based
dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
dnl We are also grateful for the helpful feedback of numerous users.

# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
