When attempting to bootstrap grep.git using
autoconf.git (v2.69-37-gb9dc6b6), I see this failure:
autoreconf: running: aclocal -I m4 -I m4
configure.ac:81: error: AC_PROG_CC cannot be called after AM_PROG_CC_C_O
../../lib/autoconf/c.m4:1459: AC_PROG_CC_STDC is expanded from...
m4/gnulib-common.m4:229: gl_PROG_CC_C99 is expanded from...
m4/gnulib-comp.m4:34: gl_EARLY is expanded from...
configure.ac:81: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
aclocal: error: /p/bin/autom4te failed with exit status: 1
autoreconf: aclocal failed with exit status: 1
./bootstrap: autoreconf failed
I worked around it by making this change.

Subject: [PATCH] build: use AC_PROG_CC_STDC rather than AC_PROG_CC
* configure.ac: Use AC_PROG_CC_STDC rather than AC_PROG_CC,
to accommodate autoconf-2.69-37+.
