[NumPy-Tickets] [NumPy] #1382: Sun compiler flags not correct for 64 bits compile

the problem is that with the given numpy version there was no
option to force a 64 bit compile on a Solaris machine capable of running and compiling
64bit code.

The flags I used may be system-specific, but did the the trick with Studio 9 and
an Ultra Sparc architecture.

I think there should be a general option fo configure for 32/64 bit compile if this information
could not be determined from other sources (e.g. from Python).

Best regards,

 This looks like you're just adding flags that work on your specific  system. For example -xtarget has a default "generic" which works on all  systems, while specifying "ultra" may not always work (for example,  there's also an "opteron" target). Same for -xarch. I think you are stuck  to patching distutils before install here if you want more optimized  compilation.

 Please reopen if I misunderstood.
