Does Boost support Windows 98?

Hello, I realize this is a rather ambiguous question, but I thought I'd start somewhere: Does Boost support Windows 98? If it's only partial support, what is missing? (I realize that there are many Boost libraries, and this answer might be a per-library question.) I see vague references in email lists to win98 support, but I'm hoping to find an official reference. I am managing a software development project based on MinGW/Boost, hoping to not have to support Win98, but I just realized that now we need to do so (support win98). Hence my question comes a bit after the fact. Thanks for any help, -Matt
