I know for certain that an application that uses Boost.Regex can be built with Visual C++ 7.1 on XP and run on Win98. It uses Unicode, so requires the Unicows DLL (http://www.microsoft.com/globaldev/handson/dev/mslu_announce.mspx) on Win98. However, I have no experience of MinGW.

I know that Win98 is not really supported, but is there any chance that libraries (specifically thread and regex) that were build on WinNT using MinGW work on Win98 (in MinGW)?

My guess is no, but has anyone tried it?

thanks
