I'm getting a weird error during bootstrap in boehm-gc:
- -------------------------- 8< --------------------------
/home/ranmath/src/gcc/build/./gcc/xgcc -B/home/ranmath/src/gcc/build/./gcc/ -B/h

/home/ranmath/src/gcc/gcc/boehm-gc/dbg_mlc.c:994: error: '[*]' not allowed in ot
her than function prototype scope
make[3]: *** [dbg_mlc.lo] Error 1
- -------------------------- 8< --------------------------

However, dbg_mlc.c:994 contains innocuous-looking code:
- -------------------------- 8< --------------------------
 991 /* This assumes that all accessible objects are marked, and that        */
 992 /* I hold the allocation lock.  Normally called by collector.           */
 993 void GC_check_heap_proc()
 994 {
 995 #   ifndef SMALL_CONFIG
 996 #     ifdef ALIGN_DOUBLE
 997         GC_STATIC_ASSERT((sizeof(oh) & (2 * sizeof(word) - 1)) == 0);
 998 #     else
 999         GC_STATIC_ASSERT((sizeof(oh) & (sizeof(word) - 1)) == 0);
1000 #     endif
1001 #   endif
1002     GC_apply_to_all_blocks(GC_check_heap_block, (word)0);
1003 }
- -------------------------- 8< --------------------------

The error is issued by grokparms in c-decl.c:4852, if that helps.

Thanks,
Ranjit.
