Windows symbols may a suffix of @<arg count>.
A new macro AX_CHECK_DLL_FUNC looks for a @ sign in the function name; when
present it will verify a symbol exists with the correct argument count.
Otherwise, AX_CHECK_DLL_FUNC falls back to emulating AC_CHECK_LIB.
Enables native threads, locking, DSO loading and shared memory.
