Use path separator character of target platform for compiled-in

default paths.

* aclocal.m4 (GROFF_TARGET_PATH_SEPARATOR): New macro.
* configure.ac: Use GROFF_TARGET_PATH_SEPARATOR.
* configure: Regenerated.
* Makefile.in (SEP): Use GROFF_PATH_SEPARATOR.

* src/include/nonposix.h (PATH_SEP_CHAR): New definition.
Replace `PATH_SEP[0]' with `PATH_SEP_CHAR' everywhere.
