Subject: [PATCH 1/1] Fix musl __USE_MISC issue

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

​

The musl C library does not define __USE_MISC and so libuv (built-in dependency)

does not use the correct struct stat definition for musl.

​

The feature test macro __USE_MISC is defined by glibc if _BSD_SOURCE or

_SVID_SOURCE is defined.

​

The libuv build system enables the feature test macro _GNU_SOURCE for linux

builds.

​

Since glibc 2.19, defining _GNU_SOURCE also has the effect of implicitly

defining _DEFAULT_SOURCE - the replacement for _BSD_SOURCE and _SVID_SOURCE.

​

In glibc versions before 2.20, defining _GNU_SOURCE also had the effect of

implicitly defining _BSD_SOURCE and _SVID_SOURCE. This is also true for uClibc.

​

Alltogether, we can safely replace __USE_MISC by _GNU_SOURCE to support building

nodejs 0.10.x with the musl C library.
