- Added <fenv.h> for C99, and the (yet unimplemented) functions
feclearexcept(), fegetenv(), fegetexceptflag(), fegetround(), feholdexcept(), feraiseexcept(), fesetenv(), fesetexceptflag(), fetestexcept(), fetestround() and feupdateenv(). - Replaced the old pow() implementation. However, powf() may need to be changed to set a domain error. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15062 87f5fb63-7c3d-0410-a384-fd976d0f7a62
