CVS automake is more strict about per-target flags, which were introduced
with the refactoring of the new checksum utilities on 6.0-cvs.

$ automake --version | head -n 1
automake (GNU automake) 1.9a
$ autoreconf -v
...
src/Makefile.am:173: compiling `md5sum.c' with per-target flags requires
`AM_PROG_CC_C_O' in `configure.ac'
autoreconf: automake failed with exit status: 1
