- 0.29.0 version:
* New variables MKC_CHECK_CC_OPTS and MKC_CHECK_CXX_OPTS were
introduced for checking C/C++ compiler's options;
* Makefile.inc and Makefile.common are included after
system variables are set, in particular CC and CXX;
* CC_TYPE is now set in mk.init.mk;
* Fixes for "err" and "warn" features. Now verr(3), verrx(3),
vwarn(3) and vwarnx(3) functions are detected correctly
(the problem was seen on gcc-4.9/armv7);
* Fix support for COMPATLIB. Objects for "features" should not
be generated outside compatibility library;
* A number of fixes in regression tests: support for latest GCC,
lib64 and lib/tri-ple-ts Linuxes;
* mkc_check_custom:
- new option -e for checking stderr for emptyness,
- new option -b for printing yes/no instead of 1/0,
- additional options to compiler are passed.
- `bmake cleandir-*` to clean examples dir after %check.
