hello,

i have a prblem where invoking which causes a crash in ms-dos.

the crash does not happen in a dos window in win98, or if i boot into plain 
dos (w/o himem and emm386). detailed info is below. i must admit i did not 
investigate this very thoroughly. i just downloaded the source, and i'll 
see if a rebuild fixes this. in the mean time, i would appreciate it if 
anyone has any clues on what might be happening.

Machine:
Acer Extensa 501 DX w/ P266MMX 96 Mb RAM w/ Windows 98 Original

Here is some output if I run which in my normal MS-DOS configuration. This 
behavior is independent of the arguments to which. The problem disappears 
when I run which in a DOS window or in plain DOS with no himem or emm386.

C:\VAR>go32-v2
go32/v2 version 2.0 built Dec 24 1999 17:46:57
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your 
PATH
 but do not delete your old go32 - leave it in the PATH after this one.
Set GO32_V2_DEBUG=y in the environment to get verbose output.
