building postgres issue on SUnStudio 12
Using SunStudio 12 on SLES9 on an opteron platform:
I run into a problem using spinlocks -see below. gsql-bugs responded : use gcc (see below). It does build fine under gcc, and will build under SS12 if I disable spinlocks as suggested. Is this an issue that the SunStudo development team can address? I am looking to see if rebuilding postgres using SS12 will improve DB performance.
Thanks.
from my request at pgsql-bugs:

By and large we don't try to support nonstandard compilers on Linux.
Use gcc.
