Use __DJGPP__ to distinguish between v1.x and v2.0 or above (v1.x doesn't 
define that symbol at all, beginning with v2.0, it gets the value of the 
major revision of DJGPP which is 2 in v2.0).  You can use __DJGPP_MINOR__ 
to differentiate different releases of v2.x; in v2.0 it gets the value of 
0.

Note that currently there is no way to know what version of the library 
is linked into the program.
