No, it produces "C intermediate code".  This is the intermediate code that the
C compiler produces between pass 1 and pass 2.  According to the SVR1
manual, the f77 compiler on SysV uses
	/usr/lib/f77pass1	f77 compiler
	/lib/c1			pass 2 of C compiler
	/lib/c2			optimizer
	/bin/as
	/bin/ld

but it doesn't use /lib/cpp (the preprocessor), or the C compiler pass 1
(/lib/ccom, /lib/c0, or /usr/lib/comp, depending on version & machine).
(Actually, on a Vax 11/780 running System V, there's a /lib/f1, and the
3B-20 running SVR2 has /usr/lib/f77pass2 (documented!)).
