compiling feff8

[Alex Ankudinov <alex@leonardo.phys.washington.edu>]

Hi FEFF Users,

I have a feff8.2 version, which I am trying to compile and
test on various platforms before release.

I want to report that I had problem compiling it
for Mac OS X using Absoft compiler. For successful compilation
I had to use -N113 option, which promotes real and complex
to double precision. Code gave wrong output without that
option, and this problem may appear for other platforms.

Thus for Mac OS X using Absoft compiler feff8.* code should be compiled as
  f77 -O -f -N11 -N113 feff82.f -o feff82
where 
 -O optimization flag, which produces 1.5 times faster executable
 -f makes all code in lower case letters
 -N11 - allows 32 bit operations
 -N113 - promotes real to double precision

I hope it might help successful compilation of feff8*.f code on your
platform.
