re-adding a "unix-dev.mk". Debugging libtool output 

is just too much of a pain for me, I prefer a good old
static lib without optimizations :-)

"make devel" is back on Unix then..

LATEST CHANGES
- fixed two memory leaks:
- the memory manager (16 bytes) isn't released in FT_Done_FreeType !!
- using custom input streams, the copy of the original stream
was never released
- fixed the auto-hinter by performing automatic computation of the
"filling direction" of each glyph. This is done through a simple and
fast approximation, and seems to work (problems spotted by Werner
though). The Arphic fonts are a lot nicer though there are still a
lot of things to do to handle Asian fonts correctly..
===========================================================================
BETA-8 (RELEASE CANDIDATE) CHANGES
- deactivated the trueType bytecode interpreter by default
- deactivated the "src/type1" font driver. Now "src/type1z" is
