#294 fixed DosOpen is not high memory safe Steven Levine
Description

Some gcc applications make direct calls to DosOpen, which is not high memory safe. It would be useful if an os2safe wrapper was added.

#293 fixed emxomf - enhance to warn for out of range HLL debug index rather than die Steven Levine
Description

When building large applications, such as firefox it is possible for the HLL type index to exceed 32K. The current emxomf behavior is the die. It is recommended that the debug behavior be changed to print a warning and force the index to 0.

The attached patch is the code used to build the emxomf used to build the current firefox.

#292 fixed setlocale may not be SMP safe Steven Levine
Description

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.
