[C++-sig] warning: "_POSIX_C_SOURCE" redefined

[Ralf W. Grosse-Kunstleve]

I can reproduce the warning... but only after removing the -w from the g++
command line. 

With g++ I am always compiling with -w because I get useless warnings otherwise
that I cannot disable with other switches. I rely on EDG compilers to check my
code for standard conformance; for this purpose the EDG compilers generally do
a much better job than g++.

If you don't want to use -w (I don't know how to tell bjam to insert the -w)
you have to analyze how exactly the conflicting definitions of _POSIX_C_SOURCE
come about. Maybe we can do something with #ifdef in the right places. However,
I doubt it is worth the effort unless you can demonstrate the same problem on a
more recent platform with a more recent compiler.
