File config-replace-AC_TRY_-COMPILE-LINK-RUN.patch of Package mvapich3
commit 241a53df04b9914bc897671773c06f522ea79764
Author: Hui Zhou <hzhou321@anl.gov>
Date: Sun Apr 11 14:06:22 2021 -0500
config: replace AC_TRY_{COMPILE,LINK,RUN}
AC_TRY_{COMPILE,LINK,RUN} are obsolete, replace with AC_{COMPILE,LINK,RUN}_IFELSE.
Format the code for better readability.
