Hello

Thank you for the reply.

The default setting in config.mgw, HAVE_STRUCT_EXCEPTION_IN_MATH_H is not defined.
For math.h for 32 bit gcc complier seems not to require HAVE_STRUCT_EXCEPTION_IN_MATH_H is defined.

I have manually define HAVE_STRUCT_EXCEPTION_IN_MATH_H in config.mgw and tried compile again.

The "error: conflicting types for '_matherr'" appeared.

internal.c:63

Hmmm! What is wrong?
