assembler for various X86 platforms including Win32. It can output object files that VC++ will tolerate so it could be used to provide assembly language support to Win32 without the need for MASM. This is preliminary stuff: it doesn't even work yet.

You need to define one of
|
|
ELF - elf systems - linux-elf, NetBSD and DG-UX
|
|
OUT - a.out systems - linux-a.out and FreeBSD
|
|
SOL - solaris systems, which are elf with strange comment lines
|
|
BSDI - a.out with a very primative version of as.
