* configure.in: Move check for mkstemp() to...

* aclocal.m4 (GROFF_MKSTEMP): This new function.
* configure: Regenerated.

* src/include/groff-getopt.h: Don't use variable names in
declarations.


* configure.in: Add special check for mkstemp().
* src/libs/libgroff/tmpfile.cc: Use it.
* src/utils/indxbib/indxbib.cc: Ditto.
* src/utils/pfbtops/pfbtops.c (main): Don't use C++ comment style.
* src/devices/grolbp/lbp.h (lbpprintf, lbpputs, vdmprintf): Use
`const'.
