My understanding is that, with that rule, GC generated code from
cp-parser.h will end up into gt-cp-parser.h, together with the code
generated from cp-parser.c.  gengtype basically runs once for all
files, so has no problem putting GC generated code from multiple
input files into the same output file.

In practical terms, cp/decl.c and cp/decl.h (or cp/name-lookup.c
and cp/name-lookup.h) are in a similar situation, and work fine
with similar gengtype.c rules. :-)

Thanks
