Hi again, 

I grabbed the latest and found at least one more minor changes is
still needed for Solaris 2.5.1 (not sure if this change is portable
for other platforms that may need something like this):

1) Modify lib.h to also "#include <stdarg.h>" after line 56:
        #ifndef HAVE_SNPRINTF
        #include <stdarg.h>

Reason: Based on comments found in Solaris 2.5.1 headers, Sun
purposely doesn't declare va_list via <stdio.h> so I added the
"#include <stdarg.h>" which does what we need.  The compilation error

[groff/groff-current] ultra(1049)> make
g++ -I. -I/export/site/src/groff/groff-current/src/libs/libgroff
    -I/export/site/src/groff/groff-current/src/include -DHAVE_CONFIG_H
    -R/site/gcc/default/lib  -c font.cc
In file included from font.cc:22:
/export/site/src/groff/groff-current/src/include/lib.h:55: type
specifier omitted for parameter
*** Error code 1
make: Fatal error: Command failed for target `font.o'

2) Using Sun's make breaks on pic.y but gmake works...

/export/site/src/groff/groff-current/src/include/lib.h:32: parse error
before `}'
In file included from pic.h:22,

** NOTE (thoughts on the problem but no fix): make ends up using gcc
to compile instead of g++, I suspect this is just an incompatibility
somewhere in the makefile for moving the file to pic.cc, but a simple
workaround for this problem is to use something like:
        make CC=g++ or use gmake

I suspect this might need a makefile tweak to still work with make but
I don't have a patch for that and I have no issue with using gmake :-).

However, later on things again seem to break without gmake so maybe
it's not worth going on any more about problems using Sun's make?
