Error building PHP7 from source using Cygwin on Windows

[Jakub Kubíček <kelerest123@xxxxxxxxx>]

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.
