// gthr-single.h which is a correct way to express no threads support

#endif
|
|
// Define __USE_MALLOC after this point in the file in order to aid debugging
|
|
// or globally change allocation policy. This breaks the ABI, thus
|
|
// completely recompile the library. A patch to better support
|
|
// changing the global allocator policy would be probably be accepted.
