* Makefile.in: Build wincap.o.

Browse Source 
* wincap.cc: New file.
        * wincap.h: Ditto.
        * autoload.cc: Add dynamic load statement for `CreateHardLinkA'.
        * dcrt0.cc (os_being_run): Eliminated.
        (osname): Ditto.
        (iswinnt): Ditto.
        (set_os_type): Ditto.
        (dll_crt0_1): Call wincap.init() instead of set_os_type().
        (_dll_crt0): Ditto.
        * environ.cc (set_chunksize): New function.
        (parse_thing): `forkchunk' setting now invokes function `set_chunksize'.
        * fork.cc (chunksize): Eliminated. Moved to be member of wincap.
        * host_dependent.h: Removed.
        * syscalls.cc (_link): Try using `CreateHardLinkA' first, if available.
        * cygheap.cc, dcrt0.cc, delqueue.cc, dir.cc,
        environ.cc, fhandler.cc, fhandler.h, fhandler_console.cc,
        fhandler_mem.cc, fork.cc, mmap.cc, net.cc, pinfo.cc, pinfo.h,
        security.cc, syscalls.cc, sysconf.cc, syslog.cc, thread.cc,
        times.cc, tty.cc, uinfo.cc, uname.cc, winsup.h: Use new wincap
        capability check throughout.
        * winsup.h: Include wincap.h. Eliminate extern declarations of
        `os_being_run' and `iswinnt'. Eliminate `os_type" definition.
        * include/cygwin/version.h: Bump version to 1.3.4.
