[pkg-boost-devel] Bug#367825: Patch for bjam segfault with g++-4.2

[Daniel Schepler]

I found that if bjam was compiled with -fno-strict-aliasing, it didn't 
segfault anymore.  It seems the hash table code is what's violating the 
strict aliasing rules.

I've attached a patch to turn on -fno-strict-aliasing, for the main compile as 
well since even under g++-4.1 some of the libraries (like boost-python) 
tripped those warnings as well.  I also fixed a few implicit declaration 
warnings and so on that might have caused trouble on 64-bit systems.

I'll hold off on adding the "patch" tag until I've tested that the entire 
build works OK.
