Nevermind, figured it out: I had watt32 installed in my global include
path, which redefines these macros in sys/cdefs.h. Removing those
headers resolved the issue.
In case anyone is interested in the build script I used, see the link
below. It's a fork of Andrew Wu's build-djgpp script, which I modified
for more customizability and to build various other cross-compiler
targets (alongside djgpp).
