#		-l library	(passed to ld).

#		-u		complain about undeclared variables

#		-w		omit all warning messages

#		-w66		omit Fortran 66 compatibility warning messages

#		files		FORTRAN source files ending in .f .
#				C source files ending in .c .
#				Assembly language files ending in .s .
#				efl source files ending in .e .

#		-D def		passed to C compiler (for .c files)

#		-I includepath	passed to C compiler (for .c files)

#		-Ntnnn		allow nnn entries in table t
