This is RSX, the DPMI-extender for EMX and DJGPP programs.

RSX can run the GCC programs under DPMI-servers like MS-Windows 3.1

and simulates a missing 387/487.



News in release 5:

	- 32 bit RSX extender default now

	- pipes, software scheduler; 'gcc -pipe' works

	- rsx can run Emacs 19.27 (emx)

	- new emx syscalls (select, bsd signals, pipe)

	- tested with OS/2 Warp; _memaccess() workaround

	- int10 vesa support

	- bugs fixed





UNZIP RSX-ARCHIVE:

    First you should delete older RSX versions.

    Unpack this archive with unzip50 or pkunzip2



	C:\> UNZIP   A:\DPMIGCC5.ZIP

	C:\> PKUNZIP -d -) A:\DPMIGCC5.ZIP





Please read INSTALL.TXT in this archive before using this software.





WHY USING RSX FOR EMX PROGRAMS:

-------------------------------

RSX can run unmodified EMX 0.8-0.9a programs under DPMI 0.9/1.0.

The compiler and other EMX programs can run in a MS-Windows or OS/2 DOS-box.

Also RSX supports system calls that are not available under EMX+DOS.





WHY USING RSX FOR DJGPP PROGRAMS:

---------------------------------

RSX can run the DJGPP 1.08-1.11 compiler under DPMI 0.9/1.0.

You don't need a coprocessor, a FPU-emulator will do this job.

RSX support also ptrace(), signal(), wait(), fork(), spawnve(P_DEBUG).

If you use the DJGPP compiler only under DPMI, gcc + rsx is faster than

gcc + go32.
