Subject: [PATCH 5/6] utils/pmx/pmx-src/libf2c/f2c.h: remove unnecesary macro
 for abs()

On POSIX systems, abs() is a function provided by your C Standard library,
so we don't need to define it as a macro.  It is dangerous to do so because
if f2c.h is included before stdlib.h, then then macro breaks the function
prototype.
