- New, unified implementation of POSIX permission and ACL handling. The
new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and
they allow to inherit the S_ISGID bit. ACL inheritance now really
works as desired, in a limited, but theoretically equivalent fashion
even for non-Cygwin processes.
To accommodate Windows default ACLs, the new code ignores SYSTEM and
Administrators group permissions when computing the MASK/CLASS_OBJ
permission mask on old ACLs, and it doesn't deny access to SYSTEM and
Administrators group based on the value of MASK/CLASS_OBJ when
creating the new ACLs.
The new code now handles the S_ISGID bit on directories as on Linux:
Setting S_ISGID on a directory causes new files and subdirs created
within to inherit its group, rather than the primary group of the user
who created the file. This only works for files and directories
created by Cygwin processes.

Not sure if this is wanted, but on a couple of occasions recently I have been
presented with strace output which contains an exception at an address in an
unknown module (i.e. not in the cygwin DLL or the main executable), so here is a

interpret such straces.
