coreutils/configure.ac
Paul Eggert 1314a5e7d3 (AC_PROG_CC_STDC): Use this instead of AC_PROG_CC, so that
we get a standard-conforming compiler.  This relies on the new
m4/c.m4 file.  Note that it's a bit tricky, since c.m4 doesn't
define AC_PROG_CC_STDC; we are relying on Autoconf 2.59 internals.
m4/c.m4 can go away with Autoconf 2.60 comes out.
