/* Temporary hack to get around the thread-unsafe new/delete in cygwin
|

* gcc 2.95.3. This should all be binned at the first opportunity,
|
||
|
|
* e.g. gcc 3.1 or sooner.
|
||
|
|
*
|
||
|
|
* The trick here is to do contruction via malloc(3) and then the
|
||
|
|
* placement new operator, and destruction via an explicit call to the
|
||
|
|
* destructor and then free(3).
