Subject: go32.exe (v 1.10) bug?

/* 

  The Problem:

  While upgrading my version of GCC from /pub/msdos/djgpp on
  omnigate.clarkson.edu. I ran into a problem with graphics
  applications. The short program below reproduces the problem. It
  compiles and works fine with the old GCC/GO32 release I was using, and
  compiles but does not switch to graphics mode when used with the new
  release. I think that the problem is in go32.exe as the program
  works when the go32x.exe VESA DOS extender (hacked go32 1.09) from
  gmvsa001.zip is used in place of go32.exe (using either tseng4k or
  vesa drivers). Has anyone else experienced this problem?

  Hardware:

    Gateway 2000 - 486 DX/33MHZ - 4MB RAM, Crystal Scan 1024NI
    monitor, Diamond SpeedStar SVGA card w/ 1MB ram.

  Old release:

    gcc    - version 2.1
    go32   - version 1.06
    gas    - version 1.38

  New release:

    gcc    - version 2.4.1
    go32   - version 1.10
    gas    - version 2.11
 
  Environment:

    EANSI.SYS loaded
    GO32=ansi driver c:/gnu/drivers/tseng4k.grd gw 1024 gh 768 2r1
    COMPILER_PATH=c:/gnu/bin
