* src/complete.c: obsolete hack for OS/2 and NT removed.
Completion works for NT now (not very good)
* src/main.c: HOME variable is respected by NT and OS/2
versions. If it is missing, we use LIBDIR on OS2_NT and "/"
on Unix.
* src/key.h: SHIFT_PRESSED is set to 0x0010 on NT. This value
doesn't conflict with definitions for ALT and CTRL, but it is
SDK-compatible.
* vfs/vfs.h: Minor changes for OS/2. EMX defines mkdir with
2 arguments
* vfs/tcputil,c, vfs/utilvfs.c: signal.h was includes twice.
* vfs/Makefile.in: undelfs.h is not used and should disapper
* slang/slos2tty.c: new file, copied from SLang-0.99.38,
needed for OS/2 port
* slang/Makefile.in: added slos2tty.c
* vfs/extfs/README: annoying spell errors corrected
* src/main.c: --termcap disabled for OS2_NT because it doesn't
(and cannot) work. ARCH_FLAGS is not needed anymore.
* src/text.c: most includes removed. Added a warning is someone
compiles this file with HAVE_X. Improved color scheme for
consoles with 16 background colors (e.g. OS/2). Hack for OS/2
removed.
* src/util.c, src/util.h: STRCOMP and MC_ARCH_FLAGS are moved
to util.h. It may be useful to use them for filenames' completion
on OS2_NT
