Status: O

Just to clear up a few things:

Gcc 2.0 should be omre cfront compatible.

>3.  Does not support DPMI 1.0 ( does it now? )
*Windows* doesn't support DPMI 1.0.  Go32 will have DPMI 1.0 support as
soon as I get a server to test it against.

>Pros:

>3.  Supports VCPI, XMS, int15h, and DPMI 0.9.
DPMI 0.9 does not provide enough functionality to support go32.

Yeah, the target audience is Unix programmers who are sick of porting
their 32-bit gcc sources to 16-bit DOS sources.

I'm hoping that nothing serious will happen requiring a 1.06 version,
as I'd like to concentrate on the 2.0 version of go32, which
(hopefully) will include multitasking, signals, pipes, etc.  The FSF
has my source diffs for MS-DOS, so gcc 2.0 is already ported to go32.
As soon as it's released I'll have a new cpp/cc1/cc1plus/gcc
available.
