Problem Description: 

This patch fixes multiple problems in one set of libF77 replacements.


NOTE: the yacc/lex name fixes are in the SUN3 and SUN4 versions only
      the 16k record limit fix is in ALL versions


1) yacc/lex symbol name collisions (1004552):

	Fortran 1.3.1 libF77 contains yacc and lex names _yyparse, 
	_yyerror, _yylex, _yyact etc. This is causing a conflict when 
	users try to link their own code generated by lex and yacc.


2) 16k record limit problem (1042114):

        Fortran programs get segmentation violation errors (with core
	dumps) when writing records of 16kb or greater.  This problem effects
	all styles of I/O except list-directed.

	The 1.3.1 RTF mentions I/O records longer than 8k fail unless compiled
	with -Bstatic. Even with -Bstatic, records larger than 16k fail.


INSTALL: 

Note: this assumes your Fortran 1.3.1 is installed under /usr/lang.
      you will also need to be logged in as root before issuing the
      following commands.

	These first 4 commands preserve the original static libraries

	mv /usr/lang/SC0.0/libF77.a /usr/lang/SC0.0/libF77.a.FCS		
	mv /usr/lang/SC0.0/libF77_p.a /usr/lang/SC0.0/libF77_p.a.FCS
	mv /usr/lang/SC0.0/misalign/libF77.a /usr/lang/SC0.0/misalign/libF77.a.FCS
	mv /usr/lang/SC0.0/misalign/libF77_p.a /usr/lang/SC0.0/misalign/libF77_p.a.FCS

	This next sequence copies the patch to the appropriate places
