Bug #10629

Compile error in signal.c: ‘received_signal’ undeclared
Description
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.
