commit f47a8cdd25 introduced an
alternate mechanism for access to runtime page size for compatibility
with early stages of dynamic linking, but because pthread_impl.h
indirectly includes libc.h, the condition #ifndef PAGE_SIZE was never
satisfied.
rather than depend on order of inclusion, use the (baseline POSIX)
macro PAGESIZE, not the (XSI) macro PAGE_SIZE, to determine whether
page size is dynamic. our internal libc.h only provides a dynamic
definition for PAGE_SIZE, not for PAGESIZE.
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
