Using the "gcc-4.2-20051217" core snapshot on Mac OS X 10.4.3, using the Apple
gcc 5026 (4.0 based) as the bootstrap complier.
After doing a "make" in a separate build directory, following by a "make
distclean", config caches are left behind in fixincludes/. A subsequent attempt
to configure and bootstrap in that directly will fail because "make distclean"
did not actually leave the directory in a pristine state.
Steps to reproduce:
1) Config as above
2) Extract gcc-core-4.2-20051217.tar.bz2 tarball
3) In a separate build directory:
$ mkdir gcc-build
$ cd gcc-build
$ ../gcc-4.2-20051217/configure --enable-languages=c --disable-checking
--prefix=/usr/local/foo
...
$ make
4) Run "make distclean" and note left-over files
$ make distclean
rm -rf stage1-*
rm -rf stage2-*
rm -rf stage3-* compare
rm -rf stage4-* compare3
rm -rf stageprofile-*
rm -rf stagefeedback-*

$ make
