Re: PATCH: non-GNU make broken again during `make bootstrap'

Regarding the breakage found with the patch of this thread, Alexandre
Oliva <aoliva@redhat.com> wrote on gcc-bugs:

The issue is not what fixinc needs in any particular stage but rather
passing all the values that must be consistent across any recursive
make calls.

This patch moves us forward (tested by me and Robert L.):

2001-10-03  Loren J. Rittle  <ljrittle@acm.org>

        * Makefile.in (STAGE2_FLAGS_TO_PASS): Propagate HOST_CFLAGS,
        HOST_LDFLAGS and HOST_CPPFLAGS.

  STAGE2_FLAGS_TO_PASS = \
  	HOST_CC="$(HOST_CC)" \
+ 	HOST_CFLAGS="$(HOST_CFLAGS)" \
+ 	HOST_LDFLAGS="$(HOST_LDFLAGS)" \
+ 	HOST_CPPFLAGS="$(HOST_CPPFLAGS)" \
  	CFLAGS="$(BOOT_CFLAGS)" \
  	LDFLAGS="$(BOOT_LDFLAGS)" \
  	WARN_CFLAGS="\$$(GCC_WARN_CFLAGS)" \

Installed on mainline.  Awaiting approval for 3.0 branch as per
Alexandre's statement.  I am just as willing to roll back the
STAGE2_FLAGS_TO_PASS part of the changes in Makefile.in on branch if
that is considered less risky (however, that means gcc 3.0.2 will not
build with BSD make unless someone else figures out an alternate safe
patch before release).
