musl - an implementation of the standard library for Linux-based systems
536c6d5a42
the old idiom, f->mode |= f->mode+1, was adapted from the idiom for setting byte orientation, f->mode |= f->mode-1, but the adaptation was incorrect. unless the stream was alreasdy set byte-oriented, this code incremented f->mode each time it was executed, which would eventually lead to overflow. it could be fixed by changing it to f->mode |= 1, but upcoming changes will require slightly more work at the time of wide orientation, so it makes sense to just call fwide. as an optimization in the single-character functions, fwide is only called if the stream is not already wide-oriented. |

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
