compiling my new project using Coridium's Windows-based tools under Linux. it couldn't find the DLLs, so after googling a bit it turns out it looks for them under PATH; but it's the Windows PATH variable, which has nothing to do with Linux's. and to set Windows's PATH you have to edit the registry. not acceptable.
so I played with different things. WINE_PATH no help. WINEPATH yes! if you set it to a Windows-style path, it gets prepended to PATH:
jcomeau@aspire:~$ WINEPATH="c:\\bleah;d:\\yuck" wine cmd CMD Version 1.4.1Z:\home\jcomeau>path PATH=c:\bleah;d:\yuck;C:\windows\system32;C:\windows;C:\windows\system32\wbem
