Hi Pierre, (Btw. you got the wrong Christian as CC. ;-))

Anyway, calling it once should not cause any performance problems at all. > Can you explain why we need it and what tests are affected by this > change please? This ensures that FPUs on x86 systems are definitely in double precision mode. The default situation on Windows with MSVC is that the FPU is already in double precision setting as far as I've tested it - however there are situations (PHP embedded into a webserver for example) where this may not be true. Could you please provide some details for "significant performance impact"?
