[Developers] compiling ADMB with clang

[dave fournier]

I tried to compile ADMB with clang.  After a few files the make crashed 
with the message

      fatal error: 'fstream' file not found


There appear to be header file problems.  Has anyone successfully used 
clang to compile ADMB?

clang -v outputs

clang version 2.8 (branches/release_28)
Target: x86_64-pc-linux-gnu
Thread model: posix
