Added for the (e)ps(la)tex family:

ChangeLog.0-2000-11-20  Petr Mikulik  <mi...@ph...>
ChangeLog.0-
ChangeLog.0-    * src/: color.c pm3d.c term.c term_api.h
ChangeLog.0-      term/: epslatex.trm pslatex.trm post.trm
ChangeLog.0:    pm3d: added 'FILE *postscript_gpoutfile' which is set to
ChangeLog.0-    'PSLATEX_auxfile' or 'gpoutfile' or '0' according to 'set term',
ChangeLog.0-    i.e. to the file where the postscript code goes to (if outputted).
ChangeLog.0:    Condition 'if (!postscript_gpoutfile)' can be used to distinguish
ChangeLog.0-    postscript terminals family (used in postscript optimized output
ChangeLog.0-    in pm3d).

That's why I think your epslatex should use it as well. Now I see that the
surrounding #ifdef PM3D ... #endif should be removed, and that
postscript_gpoutfile should be always useable.

See also here:

term_api.h-#ifdef PM3D
term_api.h-/* Output file where the PostScript output goes to.
term_api.h-   In particular:
term_api.h:     postscript_gpoutfile == gpoutfile
term_api.h-             for 'set term': postscript, pstex
term_api.h:     postscript_gpoutfile == PSLATEX_auxfile
term_api.h-             for 'set term': pslatex
term_api.h:     postscript_gpoutfile == 0
term_api.h-             for all other terminals
term_api.h-   It is non-zero for for the family of postscript terminals, thus making
term_api.h-   this a unique check for postscript output (pm3d has some code optimized
term_api.h-   for PS, for instance).
term_api.h-*/
term_api.h:extern FILE *postscript_gpoutfile;
term_api.h-#endif
