GCC 15.1 released. Many changes, some breaking.

[Tom McDermott]

The GNU COmpiler Collection (GCC) recently released version 15.1.

A copy of the release announcement is at: https://lwn.net/ml/all/aAtlfgZQyPsfBPKA@tucnak/

 

This release changes the default C++ compiler version from C++17 to C++23.

That can be changed with a command line argument  ( -std=gnu17    for example ).

There are large number of compiler changes in this version:  https://gcc.gnu.org/gcc-15/changes.html

There is one change that may break existing code (for me at least). The syntax of function pointers

has been altered.  See  https://gcc.gnu.org/gcc-15/porting_to.html#c23 for description.
