I have continuously attempted to compile newer versions of GCC from source but my system continuously fails to compile the code. I am not sure if there is any recovery path to restore success for applications that had depended on these headers. Sorry for the interruption. Nobody can help you with such a vague description of the problem. What do you mean "broken"? Which header files? What happens? What command are you running, and what errors do you get? Where did you install the new GCC? Did you overwrite an old version, or install to a different location? How did you configure and build GCC? Maybe you just need to run the mkheaders script as documented at https://gcc.gnu.org/onlinedocs/gcc-14.1.0/gcc/Fixed-Headers.html
