/* Until 2.19 the __CC65__ macro was defined as (VER_MAJOR * 0x100) + (VER_MINOR * 0x10),
|
||
|
|
* which caused it to contain broken values in compiler releases 2.16 to 2.19. The
|
||
|
|
* macro was fixed some time after 2.19 to (VER_MAJOR * 0x100) + VER_MINOR.
|
||
|
|
*
|
||
|
|
* The following strategy can be used to still compare for less or greater versions,
|
||
|
|
* should this really be necessary or wanted - it is not recommended afterall.
