New Revision: 1742
Modified:
branches/bleeding_edge/SConstruct
Log:
Add an option to the SCons build to control Microsoft Visual C++ link-time
code generation.
Turning off Microsoft Visual C++ link-time code generation makes linking on
Windows significantly which is convenient during development. There has
also been a request from embedders for a way to control this for embedding
application which does not use link-time code generation.
The name of the option is msvcltcg and the default value is 'on' to keep
the same behaviour as before.
