|
- Revert the following patch from 2.2.0:
|
|
When started from a non-Cygwin process, check if $HOME starts with a
|
|
slash (absolute POSIX path). Otherwise ignore it.
|
|
|
|
- Fix output of /proc/cpuinfo in terms of cpu topology and cache size for
|
|
modern CPUs and modern Windows OSes supporting more than 64 logical CPUs.
|
|
|
|
- Don't try to perform RFC2307 owner/group mapping on Samba/NFS if account
|
|
info is only fetched from local passwd/group files.

|
|
|
- Precautionally fix a potential data corruption problem in pipe I/O, only
|
|
actually observered in Wine yet. However, MSDN language indicates this
|
|
might be a problem on real Windows as well.
