Would dropping use of feraiseexcept and replacing it with simple arithmetic that generates the desired exception flags be a viable solution? -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
