Subject: Add -fdelayed-template-parsing option. Using this option all
 templated function definitions are parsed at the end of the translation unit
 only if it is required by an actual instantiation. As such all the symbols of
 the TU are available during name lookup.

Using this flag is necessary for compatibility with Microsoft template code.
This also provides some parsing speed improvement.
