[Boost-users] Do the Range Adaptors really depend upon the RegEx static lib?

Hello, I'm using the range adaptors from the latest version of the range library in the vault. Namely: boost::adaptors::filtered boost::adaptors::transformed The Visual Studio linker was kind enough to inform me that these depend upon the regex static library (libboost_regex-vc80-mt-sgd-1_38.lib). Does anybody know why? I'd rather not build the boost regex lib. Is there any way to avoid this dependency?
