[Rd] building a libR.a for BlueGene/L

[Sean Hill]

We would like to compile a minimal R library that could be linked  
into an application that will be run on a BlueGene/L system with  
8,192 processors. This is a system that requires no shared libraries,  
no graphical interface, must be single threaded, and will be cross- 
compiled.  I would statically link the code for the packages we require.

 From looking through the code, it seems like it should be possible  
to build such a version.  However, it would be invaluable to have the  
advice and aid of the people who truly know this software.

Thus far, I have configured the build to use the appropriate  
compilers.  I had to tell configure that it was crosscompiling by  
editing the config.site file (it didn't recognize that it was).   
However, I am currently hitting a roadblock with configure failing  
with the report:
WARNING: blrts_xlf and blrts_xlc disagree on int and double
configure: error: Maybe change CFLAGS or FFLAGS

The last lines in config.log are:
#ifdef __cplusplus
extern "C" void exit (int) throw ();

configure: exit 1

Thank you very much for any assistance,
Best
