[Bug-gsl] Test result for test release of gel 1.16

[Steve Brosnan]

Test results on a mid-2011 iMac (quad-core i5) running MacOS 10.8.3 follow…

As exists for gsl-1.15, (./configure; make; make check) shows multiple errors 
for SV_decomp_mod. This has been investigated previously in this forum and was 
found to be related to optimization problems with the default cc compiler on 
Apple products. Apple's preferred compiler is now 'clang'. 

Repeating the build (after make clean) using (./configure CC=clang; make; make 
check) results in the following:
Warnings issued in 'make':
...
coupling.c:167:17: warning: implicit declaration of function 'gsl_sf_exp_err_e'

Apparently clang is more picky than the standard compiler. I do not recall any 
such warnings in gsl 1.15, but I could be mistaken. I saw your comment about 
waiting to fix issues with strict compiler flags until another release. I 
understand your caution.

Since the root cause for the optimization issue has not been identified, there 
was previously some discussion about adding a note to the INSTALL file 
recommending that Mac users specify the 'clang' compiler. I did not see any 
such comment in the existing INSTALL file. I think it would be a good idea.
