More on static linkage

I have been trying to link the boost::regex library to a DLL (Release 
build) without success and I really need help.  I have learned 
something new.  Hitherto, I have put this line right above my code in 
one of my header files, i.e., within the "#if !defined()" block that 
prevents duplicate inclusion:

#define BOOST_REGEX_STATIC_LINK

This has no effect on the build whatsoever.  The resulting DLL is no 
bigger and the client will not work if you rename 
boost_regex_vc6_mdi.dll from its place.  You get an error message 
from the client saying that this file is missing.

If, however, I place the line above as the very first line in a 
header file, then, instead, I simply cannot compile and build the 
project at all.  The compile error I am getting states that there 
are "multiply defined symbols"!  I.e., the symbols defined in the 
library are being defined twice.  

This is driving me nuts.

Thanks for any help.
