Re: [patch] stephen's staging headers patch

OK, I looked at (but did not applied to my local tree yet) the patch
again this time you posted it...  I still like the change overall.

For the record, this file is completely gone:

+ ${target_builddir}/c++threads.h: ${glibcpp_srcdir}/@CTHREAD_H@ \
+                                ${target_builddir}
+       @cp ${glibcpp_srcdir}/@CTHREAD_H@ $@

This section is missing the few logic changes made since the 3.0 release:

+ ${thread_builddir}/gthr.h: 
+       cp ${glibcpp_srcdir}/../gcc/gthr.h ${thread_builddir}/gthr.h-in; \
+       sed '/^#/s/\([A-Z_][A-Z_]*\)/_GLIBCPP_\1/g' <
${thread_builddir}/gthr.h-in > $@
+ 
+ ${thread_builddir}/gthr-single.h:
+       cp ${glibcpp_srcdir}/../gcc/gthr-single.h
${thread_builddir}/gthr-single.h-in; \
+       sed 's/\(UNUSED\)/_GLIBCPP_\1/g' <
${thread_builddir}/gthr-single.h-in | sed
's/\(GCC[A-Z_]*_H\)/_GLIBCPP_\1/g' > $@
+ 
+ ${thread_builddir}/gthr-default.h:
+       cp ${glibcpp_srcdir}/../gcc/${glibcpp_thread_h}
${thread_builddir}/gthr-default.h-in; \
+       sed 's/\(UNUSED\)/_GLIBCPP_\1/g' <
${thread_builddir}/gthr-default.h-in | sed
's/\(GCC[A-Z_]*_H\)/_GLIBCPP_\1/g' | sed
's/\([A-Z_]*WEAK\)/_GLIBCPP_\1/g' > $@

Compare it to this:

!   AC_OUTPUT_COMMANDS([d=include/bits; a='[ABCDEFGHIJKLMNOPQRSTUVWXYZ_]'
!     rm -f $d/gthr.h $d/gthr-single.h $d/gthr-default.h

!       | sed 's,"gthr-,"bits/gthr-,' >$d/gthr.h
!     sed 's/\(UNUSED\)/_GLIBCPP_\1/g' <$d/gthr-single.h-in \
