Win32 is vaguely case sensitive... it will preserve the case of a particular file. But it will not allow Xxx and XXx in the same directory. Win32 is case preserving rather than case sensitive. At the same time, most file oriented functions like stat(), are case insensitive. They lower case the input name and lower case the target names before testing. Thus if you have a XXx file and check for the xxx file, the results returned will be for the XXx file. Make is confused by this, in some sense. When working on a directory, it uses (FINDNEXT() ?) to read out each filename from a directory one at a time. The value returned from FINDNEXT() is the case preserved value. At the same time, it uses stat() to determine presence of a file, which is case insensitive. Thus if you are have XXx, but want xxx, the FINDNEXT() value indicate it is not present. If there is a specific dependeny, where XXx is named in the rule, then stat() will show that XXx is present (in the guise of xxx). I did some experiments changing make to deal with this reality, but soon I gave up and just forced all files into lower case. I realized I would have to re-implement stat() to make any headway and I didn't want that much dependency on internals.

The problem seems to occur when the makefile looks for a filename or path match when it expands the expressions of kind "%.o" or "%.c". It only tries to look for files that are lower case. > > How is everybody getting around this bug?
