passing arguments by value

[Christopher D. Rickett]

just fyi, i have added support for the value attribute of f03 to my 
modified gfortran, allowing things like reals, ints, derived types, etc. 
to be passed by value.  i've been pretty busy lately, but i have begun the  
work to get the code submitted.  the work also includes the C interop 
binding stuff, which has been working for some time, and procedure 
declaration statements.  the procedure declaration statements are working 
fairly well, but they are not complete (primarily, procedure pointers are 
not working).  the by value and c interop stuff seems more complete, but 
i can't guarantee i've got it all covered.  :-)

if the paperwork gets done, perhaps i can submit things in pieces, since 
proc pointers aren't working yet?
