Conflict with HDF5 libraries

[Mark Patterson <mpatterson@physics.queensu.ca>]

Hello,

I've run into a conflict between guile (1.8.5) and HDF5 (1.8.1) on  
Fedora 10. I'll post on both mailing lists as I'm not sure who is in  
the best position to fix it.

HDF5 H5public.h near line 127 has:
   #if H5_SIZEOF_LONG_LONG>0
   #   define long_long    long long
   ... snip ...
   #endif
which is still present in the latest 1.8.2 release.

GUILE scmconfig-64.h near line 83 has:
   typedef long long long_long;
I tracked the origin of this line to gen-scmconfig.c, line 287 and it  
is present in the recent 1.8.6 release.

If HDF5 is loaded before guile, the typedef becomes:
   typedef long long long long
which confuses gcc (and me). As a temporary fix, I added:
   #undef long_long
just before the typedef in scmconfig-64. It is not clear to me which  
approach for dealing with long_long is correct or how they can be made  
to play well together.

I was trying to build MPB (http://ab-initio.mit.edu/wiki/index.php/ 
MPB) which is a nice piece of software that requires both guile and  
HDF5.

Thank you,
Mark Patterson
