[patch] php broken on Linux

[Matthias Ferdinand <mf+ml.pkgsrc-users%netzwerkagentursaarland.de@localhost>]

Hi,

there is a recent patch in php55, php56 and php70
(patch-ext_standard_php__dns.h) to address a memory leak.
It replaces a call to res_nclose() with a call to res_ndestroy(), which
is not available in glibc.

Attached is an improved version of that patch, using res_ndestroy() only
on non-glibc systems.

I don't know if the memory leak existed with glibc and if I just
reintroduced it :-)


Regards
Matthias
