Unable to compile Yara 1.6 under Cygwin

What steps will reproduce the problem?

1. Download yara 1.6; run 'configure'.
2. Run 'make'

What is the expected output? What do you see instead?

Expect to have Yara compile with no issues. Build fails with errors:

/bin/sh ./libtool --tag=CC    --mode=compile gcc -DHAVE_CONFIG_H -I.      -g

What version of the product are you using? On what operating system?

Environment: CYGWIN_NT-6.1-WOW64 HOSTNAME 1.7.16(0.262/5/3) 2012-07-20 22:55 
i686 Cygwin  // Windows 7

Yara 1.6 (yara-python-1.6.tar.gz)

Please provide any additional information below.

Suspected relation to 
http://code.google.com/p/yara-project/issues/detail?id=25. Tried various ways 
of adding #include for /usr/include/w32api/windef.h in libyara/proc.c (perhaps 
incorrectly) and could not successfully compile.
