John, thank you very much for your help.

I saw in the last version of boost (1.46) that the regex Jamfile has some of the tweaks the patch has (with mingw enabled and cygwin disabled, which is ok for me).
Maybe trying with this version is a possibility?

This means that the boost dll doesn't found the icu dll? Could you tell me which dll is searching or the approximate weight? I have a few icu dll (one of around 15MB) alongside boost_regex-mt.dll, but maybe I'm putting the wrong dll (as icu doesn't generate both .lib and .dll in the same compilation, I have to make two compilation passes with different tweaks, so maybe I'm doing something wrong in this pass).

Thanks in advance!
