R devel - Nov 1999 - configure script error (PR#321)

Submission from: (NULL) (209.81.240.221)


Line 2158 of configure is missing the ${CFLAGS} entry on the compilation of 
conftest.c to test int and double compatibility between g77 and gcc. This
didn't

show up when compiling on my K6 machine, but did on my Celeron notebook. The K6
reports as an i586 processor and the Celeron reports i686. This appears to be
the
only difference between the two builds.

The problem shows up as a failure of this test listed in the configure.log as
line 2107. After adding ${CFLAGS}, the build ran to completion normally on both
machines.

Orginal line 2158:
      if ${CC-cc} -c conftest.c 1>&5 2>&5; then

New line 2158:
      if ${CC-cc} -c ${CFLAGS} conftest.c 1>&5 2>&5; then

The configure script is autogenerated from configure.in and
aclocal.m4, so fixes by line number is not too useful. In my sources
it was now line 1987. Thanks anyway.

That'll be l.424 of the current aclocal.m4, inside
AC_DEFUN(R_PROG_F77_CC_COMPAT,<etc>.

I'll leave it for those who actually understand autoconf to check that
your fix is correct.
