I recently installed the beta for VC++ 2005 Express (MSVC 8.0), and
two warnings appear all over the place when compiling Allegro.
First, the /GB flag (optimized for blended model) isn't available.
From, Microsoft's page:
* Does Visual C++ 2005 Express Edition include the "optimizing compiler"
Yes, Visual C++ 2005 Express Edition includes the same core optimizing
compiler that will be included with all other Visual Studio 2005
editions. It should be noted that some new expanded optimization
features, including Profile Guided Optimizations, will be available
only in the Professional and above editions of Visual Studio 2005.
So it sounds like none of the 2005 versions of MSVC have the /GB flag,
but the full release versions have some "new expanded optimization"
features, whatever that may be.
For MSVC 6 and MSVC 7, the /GB flag is default so it doesn't really
need to be there anyway. (According to the /? help anyway.)
Second, tons of standard things are deprecated. To suppress those
warnings, the "/wd4996" switch should be used. However, it is not
present on MSVC6, so it can only be added on the MSVC7 and later
targets.
Attached are the outputs of cl /? for MSVC 6,7, and 8.
