I've finally gotten round to testing this with make 3.80 on a recent 
version of Cygwin, and the same problem persists, so whatever changed 
from make 3.79.1 to 3.80 had no effect.

$ make install
mkdir  C:/PROGRA~1/MICROS~4/VC98/lib
mkdir: cannot create directory `C:/PROGRA~1/MICROS~4/VC98/lib': File exists
make: *** [create-install-dirs] Error 1

$ make -v
GNU Make 3.80

I also tried to run 'make install' for MSVC 6 on DJGPP, and found that 
if UNIX_TOOLS was set to 1, the same problem would occur, but if 
UNIX_TOOLS was not set, the Allegro files would be installed. Looking at 
the output of 'make install' with UNIX_TOOLS unset revealed that there 
was no attempt to create the alredy existing directory 
C:\PROGRA~1\MICROS~4\VC98\lib . One theory I've come up with is that the 
line:
    $(foreach file, $(filter-out existing_dirs, $(INSTALL_DIRS)), \
only works for shortened DOS filenames if backslashes are being used. So 
I'm wondering if I should make a patch where if UNIX_TOOLS=1 and 
$(INSTALL_DIRS) contains shortened DOS paths, it converts the 
directories in $(INSTALL_DIRS) to backslashes and then after the 
filtering converts $(INSTALL_DIRS) back to forward-slashes? Would this 
be overkill? Is there an easier way to fix this? Also, I think this 
might only fix the problem of compiling for MSVC under DJGPP using 
UNIX_TOOLS=1 - I'm not sure if Cygwin's make even accepts backslashes 
(Cygwin is less tolerant of DOS-isms than DJGPP).
