[svn-r15639] Purpose: Check for __func__ keyword during configure
Description:
In some of the new H5EA* code, many new C99 features are being used. Most of them are portable to all compilers, but the __func__ keyword in particular isn't supported in Visual Studio on Windows. Instead, Windows defines the __FUNCTION__ keyword, which can be used as a direct substitute.
We now check for the __func__ keyword during configure and define the feature flag H5_HAVE_C99_FUNC. There was previously a check for __FUNCTION__, and the feature flags H5_HAVE_FUNCTION. In H5EApkg.h, we check for the presents of each of these in order to see which to use. If neither are avaiable, fail.
Tested:
h5committest (kagiso, smirom, linew)
