Of course!  __align__ works in DJGPP, I tested it when LSB tags were
introduced.

They don't: DECL_ALIGN works on platforms other than XP.

It isn't.  stubify simply prepends a small 2KB stub to the otherwise
COFF executable, since DOS and Windows don't know how to run COFF
images.  The stub is a DOS program that, when invoked, loads the COFF
image into memory, switches the CPU into 32-bit protected mode, and
then passes control to the entry point of the COFF image.

So stubify.exe cannot possibly break alignment of the COFF code.

I will take this problem (later today) with the other DJGPP developers
on the DJGPP developers' list and see what I come up with.
