Problem Description: 
(Rev 10)
4009327	 Fortran 77 SC4.0 seg faults.

(Rev 9)
1254811	 f77 4.0 -Xlist option does not complete, stops with
	 too many errors
1256195	 cg: assertion failed with -autopar -c in file regman_reporter.h. 
1256927  all followed READs statements yield EOF if the first read
1257337	 End-of-file is not being recognized in formatted READ

(Rev 8)
1254398  Formatted I/O performance bug
1255016  Problem building CATIA with -dalign and -O2 (cg)

(Rev 7) 
1252981	 Formatted input in fortran does not work in 4.0

(Rev 6)
1249697  Formatted read from tty works incorrectly.

(Rev 5)
1246357  An error in cg causes values in registers to be
 	 overwritten by loops generated for memory-memory copy
	 statements (e.g., Fortran string assignments)
1247503  Fortran MIN and MAX operations with common operands
	 cause cg to abort in some cases, with the message:
	 "cg: assertion failed in file ../src/codegen/map_pseudo.cc"
1243691  cg dumps core when compiling certain forms of apparently
	 infinite loops, which might actually be exited by other
	 mechanisms (e.g., a timeout signal, exit(), or longjmp()).
	 An infinite loop coded in an obvious manner, such as
	 "while(1){...}", does not elicit this behavior from cg.
 
(Rev 4)
(none)	 A test is failing with option -O2 on execution.
1243103  The performance of SC4.0 f77 is not acceptable when using the -dbl 
	 or the -r8 switches. The SC4.0 F77 compiler generates code that takes 
	 twice as long to execute on an ultra1/170 than the same code from 
	 SC3.0 F77 takes.
1243750  SC4.0 f77 OPEN with READONLY fails if file has permissions 444
(none)   A new README with fixed bug list is included.
 
(Rev 3)
(none)	 New problem in the FORTRAN BTEST function.  The 
	 problem only appears when the option "-O2" is used 
	 on the command line for the compilation.
1226041  Multiplication of long long * long gives wrong answer
1237180  Bug in software pipelining optimization causing
	 assertion failure in some cases when -xchip=ultra
	 and -xarch=v8plus were used at high optimization levels

(Rev 2)
1217686  Fix an error in the implementation of pragma weak
	 when it is combined with pragma C; implement syntax form
	 pragma weak [sun] ...
1224813  Implementation of subprogram names beginning with "_". 
1230366  Fix an error in implied-do which causes incorrect
	 execution of read statement.

special  Requests from Dessault (CATIA port):
         - unconditionally 8-byte alignment for stack variables
           under -Qoption to f77pass1
         - fix problem with N_PATCH stab which caused yabe to generate
           assertion failure

(Rev 1)
1217686	 Implement pragma weak
1220473	 Implement the extension to STOP statement as following:
         * under the option of -stop_status (-Qoption)
         * STOP n to exit with status n, for integer n
1222655  cg: cannot calculate difference between symbol ".LL4" and
         symbol "program"
1226522  cg gives unnecessary warnings on lduha and sta instructions
1226580	 Implement character operation more efficiently for CATIA;
         This is a performance improvement fix which is critical
         to CATIA.
1227358  cg gives an incorrect assertion and dies.
1227788	 Fix duplicate defined label.
