Malcolm: Usability improvements in GCC 8

Over on the Red Hat Developer Program blog, David Malcolm describes a number of usability improvements that he has made for the upcoming GCC 8 release. Malcolm has made a number of the C/C++ compiler error messages much more helpful, including adding hints for integrated development environments (IDEs) and other tools to suggest fixes for syntax and other kinds of errors. "[...] the code is fine, but, as is common with fragments of code seen on random websites, it's missing #include directives. If you simply copy this into a new file and try to compile it as-is, it fails.This can be frustrating when copying and pasting examples - off the top of your head, which header files are needed by the above? - so for gcc 8 I've added hints telling you which header files are missing (for the most common cases)." He has various examples showing what the new error messages and hints look like in the blog post.
