The problem exists only on Solaris 9 i386 as there is no uint64_t needed in
/usr/include/ia32/sys/reg.h
which is included from <ucontext.h>. At some places the usage of uint64_t is
shielded like this:

Whereas at some places it isn't:

The compilation seems to work cleanly on Solaris 9/10 Sparc and Solaris 10 i386
with
-Xc -D_XPG4_2
as the headers have been modified in Solaris 10.
I am inclined to think the header file for Solaris 9 i386 is buggy as gawk
compiles
cleanly with
-Xc -D_XPG4_2 -Duint64_t=upad64_t
