Creation of precompiled headers fails for gcc-3.4.0 on i386-pc-solaris2.8

While building a cross compiler for i386-pc-solaris2.8 (on
i686-pc-linux-gnu) with gcc-3.4.0, I came across the following errors
when it came time to build precompiled headers.  It looks like
<stdio.h> and <cstdio> have somehow selected different types for
va_list. 

Is this a missing fix-includes rule?  Has it got anything to do with
pre-compiled headers?  Should I ask on the gcc list instead?  Thanks.

The Solaris va_list.h, which is included indirectly, says:

+++ Start

#if defined(__STDC__) && !defined(__ia64)
typedef void *__va_list;
#else
typedef char *__va_list;
#endif

--- End

But if I look at the preprocessor output, I see:
