We have a bug in our configure mechanism for libjava.
Specifically, when ones sets CFLAGS to "-pipe " (note the trailing blank),
bootstrap fails as follows on i386 GNU/Linux and others:
Adding multilib support to Makefile in /cvs/gcc/libjava
multidirs=
with_multisubdir=
configure: configuring in libltdl
configure: running /bin/sh '/cvs/gcc/libjava/libltdl/configure' --prefix=/suse/gp/gcc-i386 '--cache-file=./config.cache' '--host=i686-pc-linux-gnu' '--build=i686-pc-linux-gnu' '--enable-multilib' '--prefix=/suse/gp/gcc-i386' '--with-gcc-version-trigger=/cvs/gcc/gcc/version.c' '--enable-languages=c,c++,java,objc' '--program-transform-name=s,y,y,' '--srcdir=/cvs/gcc/libjava' '--with-target-subdir=i686-pc-linux-gnu' 'CPPFLAGS=-O2 -pipe ' 'build_alias=i686-pc-linux-gnu' 'host_alias=i686-pc-linux-gnu' 'target_alias=i686-pc-linux-gnu' --enable-ltdl-convenience --with-auxdir=/cvs/gcc --cache-file=.././config.cache --srcdir=/cvs/gcc/libjava/libltdl
configure: loading cache .././config.cache
configure: error: `CPPFLAGS' has changed since the previous run:
configure: former value: -O2 -pipe <===
configure: current value: -O2 -pipe <===
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm .././config.cache' and start over
configure: error: /bin/sh '/cvs/gcc/libjava/libltdl/configure' failed for libltdl
gmake[1]: *** [configure-target-libjava] Error 1
gmake[1]: Leaving directory `/tmp/OBJ-1113-2018'
gmake: *** [bootstrap-lean] Error 2
Note that "former value" and "current value" above differ by one blank.
I tried to track the source of this difference down but failed so far. Any
concrete hints where to look or, better yet ;-), takers?

Not limited to libjava... All of it is, uhm, what's the word,
unfortunate. It triggers too often, and just doesn't do the right
thing, an rm -rf followed by another build would be preferable, as then
it would actually build all the time.
:-(

Well, it is much worse than that! For libjava, this failure reproducibly
happens when building in a pristine build tree from pristine sources.

This problem currently breaks a regular bootstrap on Tru64 UNIX, cf. PR
libgcj/18222.

I sent a followup to this PR. It would help a little to find out
whether the bug occurs when creating config.status or when running it.
