+## Boehm GC
+
+GCC includes an own variant of [[/Boehm_GC]] that is based on an upstream
+version, but with own patches, etc.  This is used for Java.  (There are patches
+(apparently not committed) that GCC itself can use it, too:
+<http://gcc.gnu.org/wiki/Garbage_collection_tuning>.)
+
+Patches to GCC's fork should be contributed back to upstream [[/Boehm_GC]].
+
+[[tschwinge]] reviewed (but only briefly for large parts) the differences on
+2010-11-17, based on 5be7963446247204245c954641290f0e5ce238c6 (2010-10-28) of
+[[source_repositories/GCC]] and for [[source_repositories/Boehm_GC]] CVS HEAD

+9abb37b2e581b415bb1f482085891a289c2c0be1.
+
+[[tschwinge]] reviewed the Debian GCC Boehm GC changes, compared them to the
+upstream code, and put it into the local *hurd/boehm-gc/config_backport*
+branch, planning to submit it to gcc-patches after testing with the GCC
+[[testsuite]].
