I've been getting sporatic errors like this since the introduction of
the modula-2 front-end:

They seem to come and go without rhyme or reason. For example build
#1885 on lm32-elf failed, while #1884 passed.
Aside from the fact that I coonfigure with --enable-languages=c,c++ and
yet modula-2 stuff still gets built (can that be fixed?) it seems like
we're missing dependencies to ensure that the generated config.h file is
made before building the modula-2 stuff.
In a good build you'll see something like this:
config.status: creating auto-host.h
[ ... ]
Build GSFIO.o:
g++ -g -c -I. -I../../..//gcc/gcc/m2/mc-boot-ch
-I../../..//gcc/gcc/m2/mc-boot -I../../..//gcc/gcc/../include
-I../../..//gcc/gcc -I. -Im2/mc-boot -I../../..//gcc/gcc
-I../../..//gcc/gcc/m2/mc-boot -I../../..//gcc/gcc/../include
-I../../..//gcc/gcc/../libcpp/include -I../../..//gcc/gcc/../libcody
-I../../..//gcc/gcc/../libdecnumber
-I../../..//gcc/gcc/../libdecnumber/dpd -I../libdecnumber
-I../../..//gcc/gcc/../libbacktrace
../../..//gcc/gcc/m2/mc-boot/GSFIO.c -o m2/mc-boot/GSFIO.o
Which naturally works just fine.
In a bad build, auto-host.h is _not_ created before trying to build GSFIO.o.
Can you please take care of this. It's rather annoying to have builds
failing in the continuous testing system like this, particularly when
modula-2 isn't even enabled.
