Most libraries do not encode half as much data as what Boost encodes in 
its versioned naming scheme.
Most libraries certainly do not care about 32 or 64 bits, it's two 
configuratons you set up and compile separately, like building for two 
different architectures.

There is, C:\Boost.
That's the default installation directory of the Boost windows installers.
Of course you cannot put both 32 or 64 bit in there without making 
subfolders.

It's a naming scheme that is used by all Intel libraries (and it's not 
even that consistent, some versions of TBB also have intel64/gc4.4 for 
example).
It's not used by all libraries everywhere.

I know of many pieces of software which use an approach like that but 
with different directory names.
Some will use a full triplet like x86_64-linux-gnu some will use weird 
names like glnxa64 etc.
