Re: [Bug-gsl] GSL failed to pass ``make check'' while compiled with LLVM

[Yan Zhou]

Thanks for your reply.

On Mac I also tested other compilers. Including intel C++ compiler. All 
successfully compiled but failed ``make check''. They give all kinds of 
different errors. Though I am a not a big fan of commercial compilers (The 
usually sucks). But at least the results confused me enough. I  has enough 
energy or time to look into the problem, whether it is a problem with all those 
compilers other than GCC or it is a portability problem with GSL. Instead I 
choose to stick with commercial library like apples' vecLib or intel's MKL for 
now.

However, thank you for all you have done and wish a better future of GSL.
