In any DLL builds you have to link against the windows libraries...

release-dll needs to be:
LNK = $(LNKDLL) $(WINLIBS) /out:$(TARGET) /IMPLIB:"$(LIB_NAME).lib"

release-libcurl-ssl-dll needs to be:
LNK = $(LNKLIB) $(WINLIBS) $(SSLLIBS) $(LFLAGSSSL) /out:$(TARGET)

debug-dll needs to be:
LNK = $(LNKDLL) $(WINLIBS) /DEBUG /out:$(TARGET)
/IMPLIB:"$(LIB_NAME_DEBUG).lib" /PDB:"$(LIB_NAME_DEBUG).pdb"

debug-ssl-dll needs to be:
LNK = $(LNKDLL) $(WINLIBS) $(LFLAGSSSL) /DEBUG /out:$(TARGET)
/IMPLIB:"$(LIB_NAME_DEBUG).lib" /PDB:"$(LIB_NAME_DEBUG).pdb"

Otherwise the linker flips out and yells about unresolved externals...

Cheers.
