According to the Ultrix man page for "cc":
The cc command always defines the C preprocessor macro
LANGUAGE_C when a .c file is being compiled. The cc command
defines the C preprocessor macro LANGUAGE_ASSEMBLY when a .s
file is compiled.
I don't know offhand how to fit LANGUAGE_ASSEMBLY into it, though it
strikes me as being useful for header files.
Also, it is supposed to define unix, bsd4_2, ultrix, mips, MIPSEL, and
host_mips; gcc appears to be missing bsd4_2 and host_mips. (I don't
know whether these are specific to the DECstation, or common to all
MIPS cpus.)
