Bug ID: 106700
Summary: O_NONBLOCK does not exist for x86_64-w64-mingw32 host
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: unlvsur at live dot com
Target Milestone: ---
This breaks x86_64-w64-mingw32 host since windows does not provide O_NONBLOCK
flag
https://github.com/gcc-mirror/gcc/commit/3f1c2f89f6b8b8d23a9072f8549b0a2c1de06b03
It should be
pipefd = open (pipe_path.c_str (), O_RDWR
#if defined(O_NONBLOCK)
| O_NONBLOCK
#endif
);
instead
