groff 1.17.2 fails to build under vax-dec-ultrix4.3

[John David Anglin]

I tried to build groff-1.17.2 under vax-dec-ultrix4.3 with g++-3.0 (primarily
as a test of this compiler).  The build fails here:

I also had a problem here:

/xxx/gnu/groff-1.17.2/src/libs/libgroff/tmpfile.cc:153: (Each undeclared

The atexit problem is a prototype problem which needs a fixincl hack.  I
did a quick hack around the mktemp problem in tmpfile.cc.

The system doesn't have either strdup or mkstemp.  It does have mktemp
although there is no prototype for it in any system include file.  The
man page says the function should not be used for "new" applications.
Its ultrix prototype should be:

extern "C" {
extern char * mktemp (char *);
}
