[Bug libgcj/21942] New: boehm-gc doesn't compile on Solaris 10/amd64

[gcc-bugzilla at gcc dot gnu dot org]

The amd64 multilib of boehm-gc doesn't build on i386-pc-solaris2.10: the
compilation fails with

/vol/gnu/src/gcc/gcc-dist/boehm-gc/include/private/gcconfig.h:435: error: parse error before '--' token

Environment:
System: SunOS cumaru 5.10 Generic_Patch i86pc i386 i86pc
Architecture: i86pc

	
host: i386-pc-solaris2.10
build: i386-pc-solaris2.10
target: i386-pc-solaris2.10
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --with-gnu-as --with-as=/usr/sfw/bin/gas --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3 --with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3 --enable-languages=c,c++,f95,java,objc,ada --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as described above.
------- Additional Comments From ro at techfak dot uni-bielefeld dot de  2005-06-06 22:56 -------
Fix:
I've added a clause to boehm-gc/include/private/gcconfig.h for
X86_64/SUNOS5 to allow boehm-gc to compile, but gctest doesn't fully work
yet (but at least as well as the 32-bit version).  Cf. PR libgcj/21940 for
32-bit gctest failures on this platform.
