Fixed this one (lstat.c).  I introduced it when doing relative
paths - didn't know the the fixpath'ed string could have both 
forward and backward slashes.

ls behavior on my home W2K system refuses to show any strangeness on
any drives.  So far only the C drive one one W2K system at work, and
only in the root directory, shows bad behavior.

the env crash is scary.  At crash it's showing using around 6Mb of
memory with the stack at the 5.5Mb mark.  Run under the debugger
The stack is at 0.7Mb area.  The crash register values change if
run under go32-v2.  It seems to be some uninitialized memory
problem?  I don't see how the stack location could change that much 
unless there was a bug in sbrk() ...

If I set the djgpp environment variable to point to a file,
if I make that file small it will still crash; if it is larger
it then runs.  (This hint was sent to me by an OpenGUI 
tester).  We get the size of the DJGPP.ENV file and malloc that,
read the file there.  Does that pepper the memory with something
that prevents a problem?  I was also told adding a malloc(1) early 
in main also prevents the OpenGUI problems.
