Subject: bug#22552: 25.1; 25.0.90 build fails on Mac OS X 10.11

On Apple Mac running OS X 10.11:

Downloaded ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-25.0.90.tar.xz
Unpacked it.
Ran ./configure
Ran make
Compile stopped with:

  CC       xml.o
xml.c:23:10: fatal error: 'libxml/tree.h' file not found
#include <libxml/tree.h>
         ^
1 error generated.
make[1]: *** [xml.o] Error 1
make: *** [src] Error 2

On my system, that file is found in:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml

This may be related to:

* configure.ac: Find libxml2 headers in Xcode SDK dir on Darwin.

I ran:

$ xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk

config.status has:

S["LIBXML2_LIBS"]="-lxml2 "
S["LIBXML2_CFLAGS"]="-I/usr/include/libxml2 "
