>Description:
On NetBSD/i386 6.1, pkgsrc/lang/gcc (gcc-2.95.3nb7) is not built.
Same failure is detected on recent pkgstc-2013Q2 bulk build on nyftp.

src/sys/sys/ansi.h is not suitable for gcc-2.96.3nb3?
Or gcc-2.95.3nb7 has problems?

Error message is here.

 But I could not find "drop support of GCC 2.x" in your commit message,
 so I felt that it was dropped accidentally.

 How about users for (cross) build tools based on GCC 2.95.x?
 For some platforms, GCC-4.x is not supported and useless.

 I didn't and won't bother with digging into the GCC tree to find out
 when they added the builtins.

 Cross-GCC doesn't use sys/ansi.h from NetBSD.

 Isn't it clear? because you killed:
 #if __GNUC_PREREQ__(2, 96)

 NetBSD's system headers don't support gcc 2.x. What are you trying to
 do? That's a really old compiler and it's never been entirely clear to
 me why it's still in pkgsrc.

 pkgsrc is not just for current NetBSD releases and gcc-2.x is the latest
 GCC for some platforms.
 For example, it is useful to analyze a issue whether it is particular issue
 for such platforms or gcc-2.x.

 Yes.
 FeeMiNT's official compiler is gcc 2.95.3.
 FreeMiNT has some issues with pkgsrc.
 To clarify what is the cause, I want to use gcc 2.95.3.

 pkgsrc-2013Q2 release announcement has FreeMiNT as supported platform,
 and I am improving FreeMiNT support now (see e-mails in tech-pkg@).
 Deleting the official compiler of supported platform is very bad idea.

 Okay, but that doesn't require running gcc 2.95 on NetBSD, does it?

 It isn't going to work unless either we re-add gcc2 stdarg support to
 NetBSD (that is going to be a tough sell) or someone implements the
 __builtin_va_* stuff for gcc 2.95. I have no idea how hard that would
 be.

 You'll also find that gcc 2.95 doesn't compile with recent gcc,
 although maybe we have patches for that in pkgsrc already.

 Surely FreeMiNT doesn't depend on the copy in pkgsrc...

 You forget that it is useful when updating some software that lagged behind.

 It can be built with gcc 3, which builds fine currently.

 BCE HA MOPE!

State-Changed-From-To: open->closed
State-Changed-By: dholland@NetBSD.org
State-Changed-When: Sun, 27 Jul 2014 04:09:34 +0000
State-Changed-Why:
I have marked lang/gcc NOT_FOR_PLATFORM on netbsd-6+, because the support
for stdarg.h as a non-compiler-builtin has been removed and isn't likely
to come back.

If anyone wants it to come back, please get a consensus from tech-toolchain
and provide a patch (and file the patch as a PR against netbsd base)... if
anyone wants to add __builtin_stdarg support to gcc 2.95 be my guest but it
seems like tilting at windmills.
