RE: compiling errors from mathcalls.h

["John Ray Thomas" <jt@xxxxxxxxxxx>]

Hi Alexandre,

I have run into the same problem porting to BeOS(which is mostly POSIX
compliant) in posix/math.h while compiling tools/ppp.

>Try adding -D_POSIX_SOURCE and -D_XOPEN_SOURCE to your compile line (under
Linux) and it should work fine.

Are these preprocessor symbols or gcc compiler flags?

Thanks,
