Hi there,
I'm not sure if there's something broken on my system(s), but here we
go. Building current gcc from HEAD "Tue Nov 13 11:39:03 UTC 2007
(revision 130136)" fails for me on i686-suse10-linux-gnu and
x86_64-suse10-linux-gnu; I'm using gcc-4.2.2 and binutils-2.18 for
bootstrapping and configured the stuff as follows:
env CC=gcc CFLAGS=-O2 CXXFLAGS='-O2 -g' GCJFLAGS='-O2 -g' LDFLAGS=-s
/bin/sh ../gcc-20071113/configure --host=$config --target=$config
--build=$config
--srcdir=../gcc-20071113 --prefix=/opt/gnu --with-gnu-as --with-gnu-ld
--enable-multilib=yes --enable-__cxa_atexit --enable-checking=release
--enable-clocale=gnu --enable-interpreter --enable-shared
--enable-threads=posix --with-system-zlib --with-local-prefix=/opt/gnu
--enable-languages=c,c++,ada,java,fortran,objc --disable-nls --verbose
(No multilibs for i686-suse10-linux-gnu, of course). Up until boehm-gc,
the build runs without issues, but here it bails out:

The generated libtool script contains a line
available_tags="CXX "
but no "--tag=whatsover" is passed when invoking libtool. Looking at other
.../Makefile.in files, it appears that one has to pass e.g. "--tag=CC"
(like most files do), or "--tag=CXX" (as in libstdc++-v3/src/Makefile.in);
this option is missing in the definition of LTCOMPILE and LINK in both
boehm-gc/Makefile.am and boehm-gc/Makefile.in .
I have absolutely no idea why apparently nobody else is seeing this,
though.
The patch below fixes it for me. OK to check in?
Cheers.

boehm-gc/ChangeLog:
2007-11-13 Manfred Hollstein <[EMAIL PROTECTED]>
* Makefile.ac (LTCOMPILE): Add missing "--tag=CC" argument;
wrap line to fit with 80 column rule.
(LINK): Likewise.
* Makefile.in: Regenerate.
