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'.

-Using unnamed characters
-------------------------
+Adding Unicode characters
+-------------------------
 
 Assume you want to use a Unicode character not provided in the list, say
 U+20AC. You need to do two things:
 
 - Add a line
 
-    ---	24	0	0x20AC
+    u20AC   24   0   0x20AC
 
   (the second column is computed as 24 * wcwidth(0x20AC)) to the file
   R.proto, or, when groff is already installed, to the four fonts files in
   $(prefix)/share/groff/<version>/font/devutf8/.
 
-- In your source file, use the notation \N'8364' where 8364 is the decimal
-  representation of 0x20AC.
+- In your source file, use the notation \[u20AC] to access it.
