[PHP-INSTALL] Error building PHP7 from source using Cygwin on Windows

Hello all!

I have problems compiling very recent PHP7 master branch. I am using Cygwin
2.0.0 on Windows NT operating system (Windows Vista Bussines). All tools
that PHP build depends on are of their most recent versions. I run
following commands to build PHP:

 $ ./buildconf --force
 $ ./configure -C --disable-all --enable-debug CC=gcc
 $ make -j1

Everything works fine, all files compile correctly, but then make executes
ld trying to link compiled objects and it fails with the following error
(added newlines to improve readability):


/usr/lib/gcc/i686-pc-cygwin/4.9.2/../../../../i686-pc-cygwin/bin/ld:
warning: --export-dynamic is not supported for PE targets, did you mean
--export-all-symbols?

ext/standard/basic_functions.o:basic_functions.c:(.rdata+0x7c98): undefined
reference to `zif___gnu_basename'

collect2: error: ld returned 1 exit status
Makefile:234: recipe for target 'sapi/cli/php' failed
make: *** [sapi/cli/php] Error 1


Can someone see what am I doing wrong? When I am building my patch on
Travis CI (invoking by a commit-push), it builds all well and passes.
