Sorry, but no. At first I get an error because you forgot to define 
va_list in std/c/stdarg.di. After copying
---
     private import gcc.builtins;
     alias __builtin_va_list va_list;
---
into the version(GNU) block, I get basically the same error message as 
before:
---

-fversion=GC_Use_Stack_GLibC -fversion=GC_Use_Data_Fixed -nostdinc -pipe

         -c lifetime.d

However, copying GDC's std.c.stdarg module over it lets it compile a bit 
further. Unfortunately, it then chokes on something else:
---
gcc -c -O -m32 core/ThreadASM.S -ocore/ThreadASM.o
gcc -c -O -m32 stdc/wrap.c -ostdc/wrap.o

                  from /usr/include/errno.h:29,

I've seen this error before when trying to get my 64-bit GCC to compile 
32-bit code[1], but I'm wondering *why* it tries to do that. I don't 
think it'll run properly (or perhaps even fail to link against 64-bit 
binaries) even *if* you get it to compile...
(Removing the -m32 and executing the second 'gcc' command manually works 
fine, by the way)
I guess the first command worked mostly because it doesn't contain any 
code outside "#if defined( __ppc__ )".

[a bit later]
After removing -m32 from CFLAGS in all relevant makefiles (and perhaps 
some irrelevant ones; the only one I left was in 
lib/compiler/dmd/posix.mak since I figured it wouldn't use that one :) ) 
  build-gdc.sh completes successfully.

I attached a patch, though I'm not sure how much use it'll be if you 
insist on your own version of std.c.stdarg ...


[1]: "-m32" means "emulate 32-bit compiler", right?
