I would like libm to be independant of the standard C library.

It looks like libc defines __infinity, isinf() and the like. Why is
that?

If it's necessary for some standard compliance, would it be possible
to redefine those symbols as weak symbols in libm?


[ I'm trying to use a program in C++/Java which uses the math lib, but
  doesn't import our libc since the jdk runs in linux emulation ]

thanks,
 Aymeric
