Message-ID: <199805080220.TAA17891@rtl.cygnus.com> (raw)
In-Reply-To: <oryawgm0sw.fsf@zecarneiro.lsd.dcc.unicamp.br>
I think the bug here is that the irix5 configurations have HAVE_INTTYPES_H
in xm_defines. <inttypes.h> is not safe to use under Irix5. If you bootstrap
using the SGI C compiler, you will get type redeclaration errors because
of conflicts between inttypes.h and sys/types.h.
Checking further, I see this is a bug introduced by Kenner's rewrite of the
mips configuration files. xm-iris5.h originally had in it
#undef HAVE_INTTYPES_H
Kenner then put this in xm_defines which is wrong, because that will define
it, not undefine it. What we really need is a xm_undefines, or failing that,
some way to mark things in xm_defines which need to be undefined. Or we
could just undo Kenner's change, and put the #undef back in xm-iris5.h.
As for the configure.in patch,
* configure.in (config.h): #define to `1' instead of nothing
it is harmless and may be otherwise beneficial, so we may as well accept it.
