** This version assumes two things:
|

|
** - the existence of select to tell if there is data
|

|
** available for the file descriptor.
|
||||||
|
** - the existence of the _cnt field in the stdio FILE struct, telling

** if there is any buffered input in the struct.
|

**
|

|
** Most Unixes have these things, so this file should work for them.

|
** However, Your Mileage May Vary.
