Re: [Bug-gsl] SV decomp failure

[Steve Brosnan]

Hi Rhys,

Success! 'make check' succeeds (all of it) with CC=clang. This is for Mountain 
Lion (OS X 10.8.2).

'clang -v' yields:
Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.2.0

I'm going to guess that clang should be chosen for OS X 10.7 and later. The 
default 'CC=gcc' should be chosen otherwise.

Good news!

Steve
