Bug #10629: Compile error in signal.c: ‘received_signal’ undeclared
https://bugs.ruby-lang.org/issues/10629#change-50558

* Author: Martin Dürst
* Status: Closed
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: core
* Target version: 
* ruby -v: ruby 2.2.0dev (2014-12-18 trunk 48886) [x86_64-cygwin]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
I got the following error when making "make up; make install-nodoc", in the compilation of signal.c, on cygwin.
Most of the lines in signal.c that mention "received_signal" have been introduced (changed?) in r48910, so I have tentatively assigned this issue to Nobu.
