Windows Application Binary Interface
Wabi

   <operating system, tool> (WABI) A software package from {Sun
   Microsystems} to allow certain {Microsoft Windows}
   applications under the {X Window System}.  Wabi 2.2 runs under
   {Solaris} on {SPARC}, {Intel}, and {PowerPC}.  Wabi works by
   providing translated versions of the three core Windows
   libraries, {user.dll}, {kernel.dll}, and {gdi.dll} which
   redirect Windows calls to Solaris equivalents.  For code other
   than core library calls Wabi either executes the instructions
   directly on the hardware, if it is Intel, or emulates them,
   either one instruction at a time or by translating a block of
   instructions and caching the result (e.g. for a loop).

   {WabiServer} allows the Windows application and X display to
   be on different computers.
