gfortran option -fno-automatic and -finit-local-zero

[Chase, Jeffrey G. (IS) (Contr)]

Hello,

First of all thanks so much for all your hard work!  I'm compiling a bunch of legacy fortran that relies on SAVE semantics from relic compilers.  I'm using the -fno-automatic option to replicate that behavior.  I also was using the -finit-local-zero option, assuming that it would initialize local variables upon first use, and then save their values in subsequent calls due to the -fno-automatic option.  However, I found that -finit-local-zero would initialize local variables to zero upon each subroutine call regardless of whether -fno-automatic was used or not.  I don't know if this is expected behavior, but I thought you may want to mention it in the gfortran man page.

Thanks again!
