Limitations and other things which are not (yet) supported:
===========================================================
djgpp2/coff
-----------
* all overlays (except Allegro pakfiles) are silently stripped
dos/exe
-------
* normal dos/exes with new exe headers
* max ~24000 relocation records (...should be enough for everyone ;-)
* exe + sys combined images
watcom/le
---------
* 16-bit selector alias fixups
* 16-bit offset relocation for objects larger than 4 KiB
* 16:16 fixups
If you need any of the above (they're very rare), send us an URL of a
test file.
* 16-bit objects are not loaded into DOS memory
* There is still a problem with the wdosx extender: if you compress a
watcom/le file which does NOT contain the wdosx extender, and after this
you bind the wdosx stub to the compressed file, then it will work.
Otherwise it won't.
* unpacked pmwlite compressed programs might not work when compressed
with UPX (this is a bug in pmwunlite)
win32/pe
--------
* writable shared sections (`--force' *may* work)
* certificates in the image
* compressing files which contain a big BSS requires lots of memory
during compression
