Hi,

I'm trying to crossbuild -current from i386 to dreamcast, but
it's aborting here: (sorry for overlong lines)

  nbmkdep: compile failed.


I suppose mkdep will pretty much ignore the warnings, so the only
problem that's still there, is the non-existance of stdbool.h.

From /usr/src/include/Makefile:

  .include <bsd.own.mk>

  .if ${HAVE_GCC3} == "yes"
  INCS+=  stdbool.h
  .endif

and in <bsd.own.mk> you can see that all archs except for sh3eb,
sh3el and vax set HAVE_GCC3 to "yes" - the remaining three set it
to "no".  So, it's no wonder that there's no <stdbool.h>.  The
question is, what's a clean way to work around this in symbolcheck.c?
I don't really have too deep knowledge about the existing
preprocessor definitions, so I don't know how to check wether the
target platform we're compiling for is sh3el in symbolcheck.c.
Does anybody have an idea how to fix this?


bye,
  Harold
