Add upstream patch to fix build issue with the musl C library, as musl
does not provide the GNU extension `strndupa()` breaking the build with
an undefined reference:
```
ipc/lib.a(network_ipc.o): In function `ipc_postupdate':
network_ipc.c:(.text.ipc_postupdate+0x39): undefined reference to `strndupa'
```
The upstream patch provides a compatibility header file adding a definition
of `strndupa` if it is not already defined.

Subject: [PATCH] compat.h: introduce compatibility header
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
Introduce a compat.h housing compatibility definitions
|
|
and macros along the lines of commit 7b49b8d having
|
|
introduced a compatibility mechanism for Lua.
|
|
|
|
First use case (and motivation) is the support for
|
|
musl (https://www.musl-libc.org/) which doesn't
|
|
bother to provide
|
|
char *strndupa(const char *s, size_t n)
|
