FYI: grep had to switch: AC_PROG_CC_STDC -> AC_PROG_CC

[Jim Meyering]

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+.
