Maybe a mismatch between the libc being linked and the headers of
<stdarg.h>?  I don't see this note in libc documentation (though I don't
know if it matters here):

   *Portability note:* For some C compilers, the last required argument
must not be declared `register' in the function definition.
Furthermore, this argument's type must be "self-promoting": that is,
the default promotions must not change its type.  This rules out array
and function types, as well as `float', `char' (whether signed or not)
and `short int' (whether signed or not).  This is actually an ISO C
requirement.


However, G_fatal_error and G_warning are declared and defined as
functions that take  (char *, ...).  Apparently functions like printf()
are declared like "printf(char *)", but defined like 
"printf(char *, ...)" -- a little trickery...

I'd suspect some kind of mismatch, do you need a special -L path for
Solaris?
