Hi/2.

setmode() works on every file handles, unconditionally. But it would be better to set the handles to text mode if they are consoles.

And, I think, setting consoles to binary mode is meaningless.

In practice, MinGW beahves like this.

This issue was encountered for

​http://mantis.smedley.id.au/view.php?id=611

which includes exceptq .trp files that imply that the locale impelementation may not be SMP safe. Locale updates are SMP safe because they are serialized. However, accesses to global locale data such as is done at:

_output.c:827

zdot[1] = __libc_gLocaleLconv.s.decimal_point[0];

are not serialized. It seems that there is a small window in localeCommit between the time localeNumericFree() is invoked and __libc_gLocaleLconv.s.decimal_point is set where the pointer is NULL and an access by some other CPU will result in an exception.

We're using ___wctype() which is checking the globals instead of the temporary copy. If this had worked, it would've wasted time and queried the char type twice.
