Remove bad defines from early days of project These definitions were causing issues with building LLVM. It is possible they also caused crashes we've seen with our MacOS ARM64 OpenMP support. 2024-07-24 19:11:21 +00:00			`#ifndef __cplusplus`

Add `dontthrow` attribute to most libc functions This will help C++ code that uses exceptions to be tinier. For example, this change shaves away 1000 lines of assembly code from LLVM's libcxx, which is 0.7% of all assembly instructions in the entire library. 2024-01-09 09:26:03 +00:00			`int systemvpe(const char , char const[], char *const[]) libcesque;`
