I've investigated this a little bit further and it seems the invalid labels are
produced by line 1252 in varasm.c:
  name = XSTR (XEXP (DECL_RTL (decl), 0), 0);

I tried building egcs with --enable-checking, but first there's a problem during
build:
_floatdidf
_floatdisf
.../../../egcs/gcc/libgcc2.c: In function `__floatdisf':
.../../../egcs/gcc/libgcc2.c:1053: ../../../egcs/gcc/fold-const.c:2838: Expect exp
ression, have 'parm_decl'

After I installed only the executables itself HTMLView.ii gives the following
error:
[root@ns1102 e]# g++ -c HTMLView.ii
In file included from Component.h:28,
                 from Menu.h:28,
                 from PopupMenu.h:28,
                 from HTMLView.h:32,
                 from HTMLView.cpp:31:
NotificationCenter.h:115: ../../../../egcs/gcc/cp/lex.c:1823: Expect identifier_node, have default_arg

Hope this helps,
Franz.
