Change PyFPE_END_PROTECT to PyFPE_END_PROTECT(v). v should be the last variable to which a floating point expression is assigned. The macro passes its address to a dummy function so that the optimizer can't delay calculating its value until after the macro. 1997-03-14 04:23:42 +00:00			`#define PyFPE_END_PROTECT(v)`
