Why use DJGPP-specific filenames with non-DJGPP programs?

Then update them. The only package left that needs PATH_EXPAND for use in 
configure scripts is Fileutils.

Because updating the SimTel packages will fix the need for this, and the code 
to implement it is very fragile and has become unmaintainable and unreliable 
due to internal changes starting in Bash 2.03 and more so in Bash 2.04. 
Chances are slim and none that this feature will be put back as-is. I am open 
to another way of handling this translation, as long as it's easier to 
maintain. The only idea I to offer (and it's a bad one) is to create a 
builtin called 'realpath', so 'realpath /dev/c/djgpp/bin' would write 
'c:/djgpp/bin' to stdout. Then do 'prog.exe `realpath /dev/c/djgpp/bin`' 


> And what about PATH_SLASH?  

It decides which directory separator is used for environment variables that 
are converted from 'c:/foo/bar' to '/dev/c/foo/bar' form. When PATH_SLASH is 
'\', PATH_SEPARATOR is ':', and PATH is 'c:\djgpp\bin;c:\windows', PATH in 
Bash is translated to '\dev\c\foo\bar'. The problem with this is Bash doesn't 
recognize '\' as a path separator, and libc's _put_path2 won't translate it 
properly. Slashes are always translated to backslashes in the exported 
environment, so PATH_SLASH serves no purpose there either.

Was it supposed to handle the '/bin/sh' problem? If so, I agree it wasn't a 
very good solution.
