From: Simon Marchi Date: Sat, 31 Oct 2020 12:30:57 +0000 (-0400) Subject: gdb: use AC_PROG_CC_STDC instead of AM_PROG_CC_STDC X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e41fda1d5fd0c6751591a547924d5013f267aa80;p=binutils-gdb.git gdb: use AC_PROG_CC_STDC instead of AM_PROG_CC_STDC `autoconf -Wall` notes that AM_PROG_CC_STDC is obsolete: Fixes this autoconf warning: configure.ac:40: warning: 'AM_PROG_CC_STDC': this macro is obsolete. configure.ac:40: You should simply use the 'AC_PROG_CC' macro instead. configure.ac:40: Also, your code should no longer depend upon 'am_cv_prog_cc_stdc', configure.ac:40: but upon 'ac_cv_prog_cc_stdc'. aclocal.m4:770: AM_PROG_CC_STDC is expanded from... configure.ac:40: the top level Since we build with a C++ compiler now, I don't think this is relevant. If you look at the messages removed from gdbsupport/aclocal.m4, it says that this functionality is now integrated in AC_PROG_CC, which we already call. So it might not even make a difference. We had a local version of AM_PROG_CC_STDC, in gdb/acinclude.m4 (only used by gdb/configure.ac), remove it. gdb/ChangeLog: * acinclude.m4 (AM_PROG_CC_STDC): Remove. * configure: Re-generate. * configure.ac: Remove AM_PROG_CC_STDC. gdbsupport/ChangeLog: * aclocal.m4: Re-generate. * configure: Re-generate. * configure.ac: Remove AM_PROG_CC_STDC.
