[boost] [foreach] Multiple definition error when linking two foreach-using units

From: Eelis van der Weegen (gmane_at_[hidden])

I've attached two (tiny) files: a.cpp and b.cpp . They compile fine, but 
attempting to link them causes the following error:

b.o(.text+0x0):b.cpp: multiple definition of 
`boost::foreach_detail_::cheap_copy(...)'
a.o(.text+0x0):a.cpp: first defined here

I'm using gcc 3.4.2 with boost 1.32 and foreach.hpp revision 1.29 from the sandbox.

Making the non-template cheap_copy() in foreach.hpp at line 322 inline solves 
the problem.

Regards,
