I've spent quite a lot of time with this toolset now, and it simply does not
work as per the docs - and I can't see for the life of me why not:

Setting STLPORT_VERSION as per the docs has no effect, fixing the obvious
bug in the toolset by changing:

STLPORT_VERSION = 4.5.3 ;

to

STLPORT_VERSION ?= 4.5.3 ;

still doesn't fix the problem. Adding some ECHO statements to the toolset
shows quite clearly that STLPORT_VERSION starts off with the correct value
but gets undefined and some point during the toolset execution - so each
subsequent time the toolset is invoked STLPORT_VERSION gets reset to the
default value. At this point I'm stumped - HELP!

Thanks,

John.
