Description

Hello,

While attempting to build Ruby 2.2.2 on Cygwin (x86_64), I got the following error:

make[2]: Entering directory '/home/bnd/ext/cc/build/cygwin64/ruby-2.2.2/ext/-test-/printf'

printf.c:23:1: error: conflicting types for 'utoa'

I was able to overcome this error by renaming the function to utoa2, though you may wish to use something more appropriate.

Thank you,
Brett
