commit 31fb174dd295e50f7c5cf18d31fcfd5fe5a063b7 used DEFAULT_GUARD_SIZE from pthread_impl.h in a static initializer, breaking build on archs where its definition, PAGE_SIZE, is not a constant. instead, just define DEFAULT_GUARD_SIZE as 4096, the minimal page size on any arch we support. pthread_create rounds up to whole pages anyway, so defining it to 1 would also work, but a moderately meaningful value is nicer to programs that use pthread_attr_getguardsize on default-initialized attribute objects.
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
