[boost] [program_options] Fix for 64 bit platforms

Hello,

attached patch has just been committed to program_options/src/cmdline.cpp. 
It fixes the test failures observed on Tru64 for the cmdline_test test and 
probably applies to all 64 bit platforms.

As a side note, there are many other incorrect uses of unsigned in this 
file which also should replaced by the correct size_type, but currently 
these uses don't cause a test failure.

Markus
