Bootstrap broken on i386-pc-mingw32

["François-Xavier Coudert" <fxcoudert at gmail dot com>]

Hi Zack, hi all,

A bootstrap of GCC mainline, rev. 123324, fails because of:

gcc -c   -g -fkeep-inline-functions -DIN_GCC   -W -Wall
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic
-Wno-long-long -Wno-variadic-macros -Wno-overlength-strings
-Wold-style-definition -Wmissing-format-attribute -fno-common
-DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../../trunk/gcc
-I../../trunk/gcc/build -I../../trunk/gcc/../include
-I../../trunk/gcc/../libcpp/include -I/home/coudert/local/include
-I../../trunk/gcc/../libdecnumber
-I../../trunk/gcc/../libdecnumber/dpd -I../libdecnumber    -o
build/rtl.o ../../trunk/gcc/rtl.c
In file included from ../../trunk/gcc/ggc.h:40,
                from ../../trunk/gcc/rtl.c:35:
./gtype-desc.h:64: error: expected identifier before ',' token

Line 64 of gtype-desc.h is the line with "gt_ggc_e_10stmt_gr,," in the
following:

gt_ggc_e_18gnat_binding_level,
gt_ggc_e_9elab_info,
gt_ggc_e_10stmt_gr,,
gt_ggc_e_20ssa_operand_memory_d,
gt_ggc_e_6subvar,

The ",," is clearly wrong; there's another one later in this same file:

gt_ggc_e_13convert_optab,
gt_ggc_e_5optab,
gt_ggc_e,,,
gt_ggc_e_10real_value,
gt_ggc_e_10VEC_rtx_gc,

I'm CCing Zack, as there was a change in that code recently (last time
I did a mingw32 build was on 2007-03-22, ie before that patch, and the
bootstrap was successful). I'm willing to help and provide any
generated files that may help to track this one down.

PS: I've launched a cross build to see if I can reproduce it there,
which would of course make it easier for tracking down.
