            Bug ID: 66471
           Summary: BITMAP is a reserved keyword on MinGW
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ismail at donmez dot ws
  Target Milestone: ---

gcc/mem-stats-traits.h has:

/* Memory allocation origin.  */
   enum mem_alloc_origin
   {
     HASH_TABLE,
     HASH_MAP,
     HASH_SET,
     VEC,
     BITMAP,
     GGC,
     ALLOC_POOL,
     MEM_ALLOC_ORIGIN_LENGTH
   };

and this fails to compile on mingw-w64 with:

Renaming "BITMAP" enum should ne enough.
