Fix for 'long long long' is too long on Fedora 10 x86_64

Hello,

A while back, someone posted a question about the error:
     /usr/include/libguile/scmconfig-64.h:83: error: ‘long long long’  
is too long for GCC
but no fix was posted. I ran into this issue and am posting my  
resolution in case anyone else runs into it.

I'm running Fedora 10 x86_64 with guile 1.8.5 and HDF5 1.8.1.

HDF5 /usr/include/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 /usr/include/libguile/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's not an elegant solution  
but it works.

The HDF5 folks said they'd think about fixing this:
