I think the first of those only produces ELF reloc, but the second is
only ELF executable. (FYI, I know nothing about ELF personally.)
Pascal Lacroix's DJGPP ELF-outputting tools are old (binutils 2.9, and
his page is a few years old [July 31, 1999!], and doesn't even have
src for the tools!). BUT ...

AS-ELF.EXE (DJP-packed, so unpack it and repack w/ UPX, heh) is very
slightly used for OctaOS (most of max16c.c -- tiny chess; also, for
core of zlib). These C files compile with any DJGPP version but (for
now) the resulting assembly (.s) files need AS-ELF to output ELF
reloc, which Octasm (OctaOS version) reads (FYI, YASM *could* be used
instead but doesn't work with Octasm yet).

OctaOS is a quite nice little boot OS, in my opinion. But most of it
is in assembly (Octasm) with very little of a standard C lib
implemented, so don't get your hopes up, DJGPP fans.

But do have fun!   :-)
