Hi All Found that when compiling GCC-4.3.2 on AIX 5.3 using either xlc or an existing gcc, it is required to set CFLAGS and CXXFLAGS to -U__MATH__. This is required for the various math functions defined in AIX clashes with those that are being defined in GCC. This is not just true for gcc, I had to include this flag in my application compilation too when using xlc to avoid math subroutine redefinition errros. Just wanted to share this. With Regards Vardhan
