* pango/pangowin32.h
* pango/pangowin32-private.h
* pango/pangowin32-fontcache.c
* pango/pangowin32-fontmap.c
* modules/basic/basic-win32.c
* examples/viewer-win32.c
* examples/pangowin32.aliases: New files. Start of a Win32
implementation. Does not work yet.

* configure.in: Chek for dirent.h and unistd.h.

* pango/pango-utils.h
* pango/pango-utils.c (pango_get_sysconf_subdirectory,
pango_get_lib_subdirectory): New functions, for better
portability, to enable installation-time choice of directory (on
Windows) instead of compile-time. Use these instead of SYSCONFDIR
"/pango" and LIBDIR "/pango".

(pango_split_file_list): Fix comment, the function splits on
searchpath separators, not commas. Use G_SEARCHPATH_SEPARATOR_S
for portability. Don't try to expand '~' as home directory on
Windows.

(read_config): Use pango_get_sysconf_subdirectory().

* pango/modules.c (read_modules): Use pango_get_sysconf_subdirectory().
Don't crash if a module file cannot be opened.

* pango/querymodules.c: Include config.h Conditionalize inclusion
of dirent.h and unistd.h. Use platform-specific shared library
extension. Use pango_get_lib_subdirectory().
