https://cygwin.com/pipermail/cygwin/2022-December/252628.html After the commit 9e4d308cd592, the performance of read from non-cygwin pipe has been degraded. This is because select_sem mechanism does not work for non-cygwin pipe. This patch fixes the issue. Fixes: 9e4d308cd592 ("Cygwin: pipe: Adopt FILE_SYNCHRONOUS_IO_NONALERT flag for read pipe.")

Bug Fixes

|
---------
|
|
|
|
- Fix an error introduced into the build process, resulting in `gcc -pg'
|
|
becoming disfunctional.

|
|
|
|
- Fix a backward incompatibility problem in the definition of the
|
|
base type of the stdio type FILE. This requires that C++ binaries
|
|
compiled under Cygwin 3.4.0 having a public facing interface using
|
|
FILE need to be recompiled.
