based on patches by Jens Gustedt. these macros need to be usable in static initializers, and the old definitions were not. there is no portable way to provide correct definitions for these macros unless the compiler supports pure imaginary types. a portable definition is provided for this case even though there are presently no compilers that can use it. gcc and compatible compilers provide a builtin function that can be used, but clang fails to support this and instead requires a construct which is a constraint violation and which is only a constant expression as a clang-specific extension. since these macros are a namespace violation in pre-C11 profiles, and since no known pre-C11 compilers provide any way to define them correctly anyway, the definitions have been made conditional on C11. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
