Synopsis: Distributed libm (msun) has non-standard error handling. Responsible-Changed-From-To: freebsd-bugs->bde Responsible-Changed-By: pst Responsible-Changed-When: Sun Oct 29 10:10:54 PST 1995 Responsible-Changed-Why: You can assign this to me. My analysis: - our CFLAGS is bogus. It gives pure IEEE non-ANSI mode. - this normally has no effect because we trap for the relevant IEEE exceptions (this behaviour is also non-ANSI) - some applications may expect to get IEEE behaviour by calling fpsetmask(). - fdlibm's "POSIX" mode is bogus. It's apparently close to an old SYSV mode designed for FPUs that don't support Infinities or NaNs. Using it would break IEEE support. - few users care about the error handling and fewer understand it. Bruce
