Description Stathis Kamperis 2009-07-16 11:10:20 UTC 
cproj(3) does a stereographic projection onto a Riemann sphere, contrary to what
c99 standard says (7.3.9.4)
Comment 1 Kaveh Ghazi 2010-04-07 15:07:00 UTC 
Any progress on fixing this?  I'm going to make GCC's __builtin_cproj optimize 
according to the standard C definition.  I'd like GCC and GLIBC to have the 
same (standard/correct) implementation.  Thanks.
