You gave a path to fc-cache. fc-list doesn't have that path. You need to
figure out where the fonts.conf lies in that setting and add the correct font
path in there. Something along those lines. Or read fontconfig source code
to see what it does on Windows....
Hi Behdad:
Thanks for your help which lead me to the solution.
What initially confused me was The fc-cache man page which says
"A cache is created which contains properties of each font and the
associated filename."
So I assumed that meant the full path name, but after reading your
remarks above I used fc-cat to access information in some of those
cache files. It appears the cache simply identifies the filename
without path consistent with what you said. So that filename is a
useful identifier for the font but not useful for actually helping
fontconfig to find where that font file is located (!)
I therefore pursued your idea of modifying the system fonts.conf which
on my system is located at $prefix/gtkplus-2.22.1/etc/fonts/fonts.conf,
where prefix is the directory where I unpacked the all-in-one Windows
binary for GTK+.
This patch to that file worked.

Note, that drive-letter form was essential. MSYS-bash also honors the
alternative /z/usr/share/fonts form specifying the full path to the
file, but that form does not work in the above file.
After the above change, under wine I ran
"fc-cache" with no options, and after that "fc-list" gave lots of
results, and my test applications for libLASi worked fine as well.
So thanks very much for your essential help that lead me to the
solution, but I do feel editing an installed system file like
$prefix/gtkplus-2.22.1/etc/fonts/fonts.conf has the feel of a
workaround for a fontconfig issue that should be addressed to make it
easier for users to specify alternative font locations on Windows
platforms such as Wine.
