direct use of CFLAGS

Autoconf 2.71's `AC_PROG_CC` nukes `CC` variable, which we don't
want.  For instance a user could specify `--with-gcc="gcc -std=c99"`
to _force_ C99 mode; but `AC_PROG_CC` just nulifies that `-std=c99`
part.

`AC_PROG_CC` is called everywhere from inside of autoconf itself via
`AC_REQUIRE([AC_PROG_CC])`.  It is not a wise idea to try avoiding
this macro at all.  We need to reroute `-std=` flags to somewhere
else.
