Asanka Herath 55b0f00d5e Windows: Check for DATA symbols when scanning .obj files
The export symbol list for ASN.1 on Windows is generated by scanning
all the .obj files and extracting the symbols defined in them.  The
generated list did not specify which were functions and which were
data symbols.  This distinction is necessary for generating correct
import library stubs.
