I made a couple of chagnes to the john.exe build rules (cygwin and mingw), 
and fixed my environment to have 'proper' location for ssl  (in 
/usr/local/ssl).  These are now building properly (the strtok_r is still a 
problem for mingw, bit I will get to that).  However, with those build rules 
changed, I am wondering if this will cause others to have build issues?  I 
am not super concerned about mingw, I likely am the only one building on 
that ruleset.  But I think cygwin is the 'normal' way people get a posix 
build under win32.

Here is the changes from Makefile.  The commented out line is the 'original' 
LD line.  For the cygwin build (the first one), all I did was add 
$(LDFLAGS), and removed -lcrypto (since it is in ldflags).  For the mingw, I 
added LDFLAGS and stripped out the leay32 (older 32 bit openssl dll link)  I 
will get a patch put together, but I still have a little work to get 
strtok_r working on mingw/VC.

# $(LD) $(JOHN_OBJS) -lkernel32 -lcrypto -o ../run/john.exe

../run/john.exe: $(JOHN_OBJS)
 $(LD) $(JOHN_OBJS) $(LDFLAGS) -lkernel32 -o ../run/john.exe
 strip ../run/john.exe

# $(LD) $(JOHN_OBJS) -lkernel32 -leay32 -o ../run/john-mingw.exe

../run/john-mingw.exe: $(JOHN_OBJS)
 $(LD) $(JOHN_OBJS) $(LDFLAGS) -lkernel32 -o ../run/john-mingw.exe
 strip ../run/john-mingw.exe
 cp ../run/john-mingw.exe ../run/john.exe
