This is RSX, the DPMI-extender for EMX/GCC and DJGPP programs.
RSX can run the GCC programs under DPMI-servers like MS-Windows 3.1 and
simulates a missing 387.

News in release 4:
	- 32bit extender (source code now compiled with EMX/GCC)
	- RSX32 has a build'in fpu-emu
	- DPMI 1.0 futures (demand paging, mapped memory, etc.)
	- file handle emulation (dup files for child processes)
	  other file types are possible (pipes, mapped files)
	- info.exe works now with RSX

! Unpack this archive with unzip50 or pkunzip2.
!    C:\> unzip a:\dpmigcc4.zip
!    C:\> pkunzip -d -) a:\dpmigcc4.zip  { '-)' disables pkzip-bug in DPMI }
!
! Many files are changed. Delete older RSX versions!


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


WHY USING RSX FOR EMX/GCC PROGRAMS:
-----------------------------------
RSX.EXE can run unmodified EMX/GCC 0.8[e-h] programs under DPMI 0.9/1.0.
The compiler and other EMX programs can run in a MS-Windows DOS-box.
You don't need a 387-processor, a FPU-emulator will do this job.
-> EMX does not support DPMI
-> EMX does not support a 387 emulator.


WHY USING RSX FOR DJGPP PROGRAMS:
---------------------------------
RSX.EXE can run unmodified DJGPP 1.08-1.11 programs under DPMI 0.9/1.0.
You don't need a 387-processor, a FPU-emulator will do this job.
RSX support also ptrace(), signal(), wait(), fork(), kill(), spawnve(P_DEBUG).
If you use the DJGPP compiler only under DPMI, gcc + rsx is faster than
gcc + go32.
-> GO32 1.11 can't use the emu387 under DPMI.
-> GO32 don't support ptrace(), signal(), fork(), spawnve(P_DEBUG) etc.
