Index: ChangeLog
from Akim Demaille <address@hidden>
Medium term goal: AC_ macros can be tested with -W obsolete.
* acgeneral.m4 (AC_RUN_IFELSE): Accept IF-CROSS-COMPILING.
(AC_TRY_RUN): Use it.
* acfunctions.m4: Start ousting AC_TRY_RUN and AC_TRY_COMPILE.
* acspecific.m4 (AC_AIX, AC_MINIX, AC_ISC_POSIX): AC_BEFORE on
AC_COMPILE_IFELSE and AC_RUN_IFELSE.
