This is a mostly straight-forward rebase of our patches on top of 13.1.0. The spec files needed a change, as GCC no longer supports STABS debug information, but we were building GCC with support for it. Highlights of this release include static `operator()`, The Equality Operator You Are Looking For and extended `constexpr` support.

Subject: [PATCH] i386: Disable math errno for SerenityOS
|
|
|
|
SerenityOS uses exceptions for math error handling, which allows the
|
|
compiler to do more optimizations on calls to math functions. This patch
|
|
has the effect of setting -fno-math-errno by default.
