The workaround is to tell the parser explicitly to use a diffent
basename for the files it creates.  The following works for me:

	  gcc -save-temps -c foo.c
	  cc1 -dumpbase foo -quiet -dr -o foo.o foo.i

The first line tells gcc to not delete the intermediate files it
creates when compiling the source.  The second line then invokes cc1
directly on the output of the preprocessor.

You need these two steps because there's no easy way of passing the
`-dumpbase' option to cc1.

Unless somebody makes the change in the GCC sources and submits them
to the GCC maintainers, it won't be fixed.  The change is simple: if
LFN is not supported, remove the extension (.c, .cc etc.) from the
basename before appending the .rtl and the other extensions used for
the other -dX options.
