I assume ".dll" is added only if "dllname" doesn't have an extension ? For example, Apple's 
QuickTIme SDK for Windows is distributed with .lib files to link with and if I look up the 
corresponding ddl in the WIndows system32 directory, it is "QuickTime.qts", not "QuickTime.dll".

It looks like the dll is not checked at link-time to see if e.g. the stdcall-mangled names match 
and the routine is present ?

Thanks for the info, the software links now.
