commit aeeac9ca5490d7d90fe061ab72da446c01ddf746 introduced fail-safe invariants that creating a locale_t object for the C locale or C.UTF-8 locale will always succeed. extend the guarantee to also cover the following: - newlocale(LC_ALL_MASK, "", 0) - newlocale(LC_ALL_MASK-LC_CTYPE_MASK, "C", 0) provided that the LANG/LC_* environment variables have not been changed by the program. these usages are idiomatic for getting the default locale, and for getting a locale that behaves as the C locale except for honoring the default locale's character encoding.
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
