1In an attempt to speed up the Fortran 77
2compiler, we have provided a new interface between
3the fortran compiler and the portable C compiler.
4The intermediate file is binary, and the result is
5to speed up the execution of Fortran considerably.
6The changes necessary to make this work are as follows:
7
8***	The ONEPASS flag should be off for Fortran;
9	the simplest way of making this happen is to take
10	the line # define ONEPASS on macdefs, and put a
11	# ifndef FORT ... # endif around it.
12
13***	The function label from pass 1 must be put in
14	a file, fort.h.  Also,  a simple function, tlabel,
15	must be written to copy names and make labels.
16
17***	The function `where' must be defined, as well as the
18	function main (which was once on local2.c).
19	They can be defined on fort.h, or on local2.c
20	(surrounded by # ifnded ONEPASS and # endif)
21
22***	Other things from pass one may have crept into the pass 2
23	code: they must be also done, either on fort.h or
24	on local2.c surrounded by ifdefs.
25
26***	make fort  then creates the fortran interface...
