Parallelize byte compilation on MS-Windows.
lisp/makefile.w32-in (WINS_BASIC1, WINS_BASIC2, WINS_BASIC3) (WINS_BASIC4): New variables, subdivide subdirectories into 4 parts. (WINS_BASIC): Define as concatenation of the above. (compile): Subdivide into 4 separate and independent jobs that can be run in parallel. (compile0-CMD, compile0-SH): New targets for compiling COMPILE_FIRST files, which are prerequisites for the rest of the byte-compilation. (compile1-CMD, compile2-CMD, compile3-CMD, compile4-CMD): New targets for parallel compilation with cmd.exe. (compile1-SH, compile2-SH, compile3-SH, compile4-SH): Ditto for compiling under a Unixy shell.
