I agree, and a static build is what I'm looking to do.

So, then, just so that I can follow this, how would I know that bz2_s.a
is the static lib? I thought that all I needed to do was state that I
wanted to statically link libbz2.a.

Insofar as missing that .obj -> .o change... I've got:

# emx, gcc, OMF format, statically linked C runtime
gcc:
	$(MAKE) -f os2/makefile.os2 all \
	CC="gcc -Zomf -O -I." \
	CFLAGS="-Wall -DOS2 -DASM_CRC $(LOCAL_UNZIP)" \
	NFLAGS="" \
	DLLFLAG="" \
	AS="gcc -Zomf" \
	ASFLAGS="-Di386" \
	LDFLAGS="-o ./" \
	LDFLAGS2="-s" \
	OUT="-o" \
	OBJ=".o" \
	CRCA_O="crc_gcc.obj" \
	DEF="os2/unzip.def"

and I am specifying gcc as the target. Is it the CRCA_O="crc_gcc.obj"
which is causing a conflict and I need to change that to crc_gcc.o?
Ugh... Never mind; that was it (forest & trees issue).

Getting back to the bz2_s.a thing: Cold you please enlighten me as to
where you got that? My understanding was that all I needed to do WRT
bzip2 was to "dump" the sources into bzip2\ and specify the option and
modify the make line, referencing the library. Clearly, I'm missing
something else.

Thanks again, Dave!!
