Comment (by leif):
Ah, the problem arises when ''none of'' `/lib/cpp gcc cc c99` work (with
`$CPPFLAGS`), since then `GMP_CC` and `GMP_CFLAGS` will remain
'''empty''', and / but
{{{
#!sh
test "x$GMP_CFLAGS" = "x__GMP_CFLAGS" -o "x$GMP_CC" = "x__GMP_CC"
}}}
yields `false`, and
{{{
#!sh
AC_MSG_RESULT(yes [CC=$GMP_CC CFLAGS=$GMP_CFLAGS])
}}}
is executed, but '''not''' what follows (since `test -n
"$GMP_CC$GMP_CFLAGS"` yields `false`):
{{{
#!sh
# Check for validity of CC and CFLAGS obtained from gmp.h
if test -n "$GMP_CC$GMP_CFLAGS" ; then
AC_MSG_CHECKING(for CC=$GMP_CC and CFLAGS=$GMP_CFLAGS)
echo "int main (void) { return 0; }" > conftest.c
if $GMP_CC $GMP_CFLAGS -o conftest conftest.c 2> /dev/null ; then
AC_MSG_RESULT(yes)
CC=$GMP_CC
CFLAGS=$GMP_CFLAGS
else
AC_MSG_RESULT(no)
fi
fi
}}}
[[BR]]
I ended up with
{{{

checking for CC and CFLAGS in gmp.h... yes CC= CFLAGS=

}}}
(because `gcc` didn't work with `$CFLAGS` either, while `$CC` or
`__GMP_CC` from `gmp.h` would have worked).
(In the mpc-1.0.p0 spkg, we already use[d] the related
[https://gforge.inria.fr/tracker/?func=detail&group_id=131&aid=14669&atid=607
upstream patch] (included in MPC 1.0.1) fixing
[http://trac.sagemath.org/ticket/13290#comment:13 a slightly different
issue] with `GMP_CC` and `GMP_CFLAGS`, so the same holds for MPC 1.0.2.)
