Re: GNU Make 3.80 on Cygwin expanding variables improperly?

Greg,

Well diffing your correct.txt and incorrect.txt from the previous email 
you get these differences:

Now looking at the critical definitions you have:

LECTURES = \
        intro \
        shell01 \
        shell02 \
        version \
        build \
        py01 \
        py02 \
        py03 \
        style \
        qa \
        py04 \
        debugging \
        oop01 \
        oop02 \
        unit \
        re \
        binary \
        xml \
        db \
        spreadsheets \
        integrate \
        client \
        server \
        security \
        dev01 \
        dev02 \
        summary \
        ack \
        bib \
        glossary \
        extlinks \
        figurelist \
        tablelist \
        syllabus

SITES = # nothing

GFX_SUFFIX := gif jpg png
GFX_SRC := \
        $(foreach fmt,$(GFX_SUFFIX),\
          $(wildcard ./img/*.${fmt}) \
          $(foreach lecdir,${LECTURES}, \
            $(wildcard ./lec/img/${lecdir}/*.${fmt}) \
          ) \
          $(foreach sitedir,${SITES}, \
            $(wildcard ./sites/${sitedir}/img/*.${fmt}) \
          ) \
        )

There's nothing there that looks to me like it's platform specific so I 
would expect this to work correctly on both operating systems without a 
problem (BTW it would have been *really* nice if you'd narrowed this 
question down to those relevant lines before posting your question :-).

I know this is going to sound dumb, but do you actually have the same 
files in those directories on all the machines. (Counting symlinks as well).
