> Indeed. In particular, mingw toolchains don't have an alloca.h header - this should show up as failure from those jobs in CI.

I see, maybe in this case alloca.h should only be included in the `#ifndef _LIBUNWIND_REMEMBER_HEAP_ALLOC` and under `__has_include`? not sure whether this is acceptable.
or is this problem something for picolibc to solve? or the user by specifying `-include alloca.h`? how should this be fixed instead?
