Hi,

I noticed an issue with the musl headers when installing compiler-explorer for RISC-V. Try compiling this code with g++ and musl's stdbool.h

	- https://cx.rv8.io/g/Bc3AwY <https://cx.rv8.io/>

Compiler explorer uses the C++ front-end to the compiler by default

It seems the musl stdbool.h defines bool in terms of _Bool for C, but does not define _Bool in terms of bool for C++.

The gcc stdbool.h header handles both conditions and when included by C++ code it has #define _Bool bool but notes that it is a GNU extension.

My workaround was to delete the musl stdbool.h so that the GCC version is included, but it seems the header could work for C code passed through the C++ front-end with a small patch (attached). The other musl headers seem to support C++, so I think it might be nice to fix stdbool.h for C code compiled through the C++ front-end. Of course C++ code needs casts on malloc and there are several other differences such as new reserved words, however for the most part, a lot of C code can compile using the C++ front-end.
