[newlib-cygwin] cygcheck: expand common_apps list
https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=5c2a3661c1aeefb0591ce46e8ab3274f0c6d9112 commit 5c2a3661c1aeefb0591ce46e8ab3274f0c6d9112 Author: Yaakov Selkowitz Date: Thu May 23 11:47:36 2019 -0400 cygcheck: expand common_apps list An increasing number of tools are being included in Windows which have the same names as those included in Cygwin packages. Indicating which one is first in PATH can be helpful in diagnosing behavioural discrepencies between them. Also, fix the alphabetization of ssh.

[newlib-cygwin] Cygwin: Allow accessing 48 bit address space in Windows 8.1 or later
https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=e1254add73b1fb834933b38a5163d72c30c2330b commit e1254add73b1fb834933b38a5163d72c30c2330b Author: Corinna Vinschen Date: Tue Jun 4 16:58:53 2019 +0200 Cygwin: Allow accessing 48 bit address space in Windows 8.1 or later 64 bit Windows started out with a 44 bit address space due to a restriction of the AMD64 CPUs at the time. Starting with Windows 8.1, these CPUs are not supported anymore and Windows switched to the full 48 bit address space supported by AMD64. Cygwin didn't follow suit yet so mmaps are still restricted to the lower 44 bit address space. Fix that by using a system-specific upper address for mmap allocations, 44 bit up to Windows 8, 48 bit starting with Windows 8.1. While at it, move the heap by another 8 Gigs to leave some space for a potential extension of DLL address space, and restrict the mmap lower address so the heap can grow to 32 Gigs before colliding with mmaps.
