I just verified that I can install XEmacs 21.4.17 (unmodified) using
gcc 3.4.3 on Solaris 8 Sparc.  I also double-checked that it doesn't
work on Solaris 9 x86.  This could be due to a difference between
Solaris 8 and Solaris 9, but it could also be due to a difference in
behavior of gcc 3.4.3 on Solaris Sparc and gcc 3.4.3 on Solaris x86.
Further investigation reveals that the following two lines are
accepted by gcc 3.4.3 on Solaris 8 Sparc, but not by gcc 3.4.3 on
Solaris 9 x86:

 # include <stdarg.h>
 typedef void *__gnuc_va_list;

[The second line is taken from src/s/sol2.h.]  This indicates that gcc
uses different implementations of va_list on the two platforms.
