[Ns-developers] osx compiler is ugly

[L.Wood@surrey.ac.uk]

Mac OS X Leopard (intel and ppc) ships with gcc 4.0.1. Later
versions are available, but it's unlikely that users will install
them (and they introduce their own fun, e.g. gcc 4.4 deprecating
varargs.h in favour of stdarg.h)

Really, the compiler's the least of the problems. Leopard's linker
is generally regarded as... interesting.

 Is it possible to upgrade OSX-PPC compiler? may be a newer version will 
correct this compiling error. Otherwise I think it's mandatory to commit 
this ugly code if we want to support Mac with comments noticing why we 
wrote this code (for example: osx-ppc compiler gcc 4.0.1 requires this 
line to be added).
