This is because Cygwin make passes invalid paths to Emacs.

The new code seems to be making a poor choice of font for Latin-1 
characters, it is choosing a symbol font which does not contain the 
characters for me. This was triggering a bug that is also present in the 
trunk which caused the crash that Juanma experienced. The choice of font 
for other Latin characters is also not optimal, as the font used for 
ASCII contains most of these characters, but in the font-backend branch 
other fonts are chosen.

In addition to the bug mentioned above, I got another crash while 
displaying etc/HELLO which was caused by using s->face->font in 
w32font_draw. Changing it to use s->font works, but I have no idea what 
the difference is between these two, and why s->face->font would be NULL 
while s->font points to a valid font.
