[SOLVED] #error "glibc cannot be compiled without optimization"

["Robert P. J. Day" <rpjday at mindspring dot com>]

  slowly tracking down the last couple issues with this x86_64 build
and, in the last pass, i had two errors of the form:

  error: #error "glibc cannot be compiled without optimization"

while trying to build the glibc headers.  as a quick hack, i made the
following change in crosstool.sh:

--- crosstool.sh        (revision 15)
+++ crosstool.sh        (working copy)
@@ -441,7 +441,7 @@
     fi
     # Note: BOOTSTRAP_GCC is used by patches/glibc-2.3.5/glibc-mips-bootstrap-gcc-header-install.patch
     libc_cv_ppc_machine=yes \
-    make cross-compiling=yes install_root=${SYSROOT} CFLAGS=-DBOOTSTRAP_GCC $GLIBC_SYSROOT_ARG install-headers
+    make cross-compiling=yes install_root=${SYSROOT} CFLAGS="-O -DBOOTSTRAP_GCC" $GLIBC_SYSROOT_ARG install-headers

     # Two headers -- stubs.h and features.h -- aren't installed by install-headers,
     # so do them by hand.  We can tolerate an empty stubs.h for the moment.


  i have no idea whether that was the *proper* fix but it got rid of
those two diagnostic messages.  (those errors weren't fatal to the
build, but i figured it was worth dealing with them, anyway.)

  was that the right approach?  is that something that should be added
to crosstool.sh?

p.s.  i'm still getting all those error: #error "TLS support is
required." diagnostics.  still trying to figure out what to do about
those.

man, it's been a long day.
