To build for Watcom 32-bit 4GW you need the following tools:

NMAKE
TASMX
RTM (called by TASMX)
WLIB

Run 'makexr3l.bat clean'.  It will clean up old stuff (important,
since the build process depends on files getting renamed, which won't
happen if an old file is left there).  Run makexr3l again (no
command-line parameters this time).  It will build the .objs and lib.tmp
and then error out when attempting to build the library.  You will then
need to edit lib.tmp, removing the column of '-add' entries and the
empty lines.  Run makexr3l again and it will create the library.
