## AI overview

## Source excerpt

The ReactOS Build Environment (RosBE), our curated set of compilers and build tools, has just received a major upgrade. After more than 7 years of using the same and now ancient GCC 4.7.2, ReactOS is finally going to be built with the help of a modern compiler (GCC 8.4.0). Among other things, the new version better detects programming mistakes like improperly sized buffers, and comes with improved error messages to pinpoint such mistakes to the corresponding position in code.
