It almost certainly won't. The DLL will have references to the VS2010 C 
runtime that can't be resolved by VC6.

Why not build the DLL using a MinGW environment? MinGW has always targeted 
good ol' MSVCRT.DLL, for licensing reasons.

Won't work. You could force the linker to ignore MSVCR##.DLL and link 
against MSVCRT.DLL, but then you're at the mercy of all the 
implementation-dependent aspects of the C runtime not lining up (symbols 
in macro expansions, publicly-exposed structs, newer compiler intrinsics, 
etc.).

Building with VC6 or MinGW in the first place is really the only way to do 
it.
