It may be that Martin is using a different regex library (MinGW has
its own version, although it's not part of the base package).

I think this can also happen if the function is declared with
__declspec(dllimport) (which would suggest either using the wrong
version of <regex.h> or a need for a -D switch or #define).

AIUI, __declspec(dllimport) instructs the compiler to compile calls to
the function as an indirect function call, taking the address from the
__imp_* symbol in the program's import table. Import libraries provide
a normal function which just performs the indirect call.
