[GRASS5] MacOSX file name recognition bug in G6?

[William K]

(looks like Lorenzo responded on the other list, but I'll expand on it 
a bit)

On a (standard) HFS+ file system, the Mac is _case-aware_, but not 
case-sensitive.  (it stores filenames with case, but doesn't care).  
works in unicode too: á = Á, but á != a.

If the file system where the GRASS files are is UFS (not reccomended by 
most Mac users), it should be case-sensitive.

This creates porting problems sometimes, but these days I think most 
'nix developers have taken care of it when it's an issue in the source 
(ie the source including different case-sensitive files, or trying to 
create them in compilation or when running).  Then it's just up to 
non-Mac users to be aware of this (ie in your case trying to use both 
mask and MASK).


I'm a little confused here:

did the mapcalc create 'MASK' or 'mask' at this point?  That would be 
odd - it should create 'mask', since it's case-aware.
