commit 6442e914d9213a6d4fe9d58e9a33bc407e18a2aa
Author: Corinna Vinschen <corinna@vinschen.de>
Date: Sat Jun 20 19:05:51 2015 +0200
Use MINSIGSTKSZ and SIGSTKSZ from newlib for Cygwin as well
* libc/include/sys/signal.h: Move altstack macros completely
outside of rtems block.
* include/cygwin/signal.h: Remove definitions of MINSIGSTKSZ
and SIGSTKSZ here.
