AC_TYPE_SIGNAL from current autoconf can fail if CC=g++.

* aclocal.m4 (GROFF_TYPE_SIGNAL): New function.
* configure.ac: Use GROFF_TYPE_SIGNAL, not AC_TYPE_SIGNAL.
* configure, src/include/config.hin: Regenerated.

* PROBLEMS: Updated.


Update getopt files.

* src/include/getopt.h, src/libs/libgroff/getopt.c,
src/libs/libgroff/getopt1.c: Updated from GNU libc CVS.

* src/include/getopt_int.h: New file (from GNU libc CVS).

* src/include/groff-getopt.h: Updated.

* src/include/Makefile.sub (HDRS): Add getopt_int.h.


* font/devutf8/NOTES: Updated.



Bug fix for Win32 relocatable code.  Based on a patch from Keith
Marshall.

* src/libs/libgroff/maxpathname.cpp (PATH_MAX): Test for `_MAX_PATH'
also.

* src/libs/libgroff/relocate.c (DEBUG): Define it conditionally.
(searchpath) [_WIN32]: Use `_fullpath', not `realpath'.

-* My compiler fails to build src/utils/indxbib/signal.c, giving
-  messages like
-
-    signal.c: cannot convert `int (*)(int)' to `void (*)(int)'
-    for argument `2' to `void (* signal(int, void (*)(int)))(int)'
-
-  I use a C++ compiler for compiling C programs.
-
-The current version of the configure script doesn't handle C++ very
-well if used as a substitute for a C compiler.  In this particular
-case, it failed to recognize the proper return type of signal handlers.
-An easy fix is to manually edit the file `src/include/config.h'
-(created by configure), changing the line
-
-  #define RETSIGTYPE int
-
-to
-
-  #define RETSIGTYPE void
-
-Say `make clean' before restarting compilation.

 * There are many empty `Makefile.dep' files.  Is this a bug?
 
 No.  Real dependency files are created with a `make depend' call.
