6.2.17 -D__BP_RANDOM__ - BP compatible pseudo random number generator

GPC uses a more elaborate pseudo random number generator than BP does. Using the `Random' and `Randomize' functions works the same way, but there is no `RandSeed' variable (but a `SeedRandom' procedure). However, if you use the `System' unit (see section 6.2.14 - -uses=System - Swap; HeapError; etc.) and define the symbol `__BP_RANDOM__' (by giving `-D__BP_RANDOM__' on the command line), it will provide a 100% BP compatible pseudo random number generator, including the `RandSeed' variable, which will produce exactly the same sequence of pseudo random numbers that BP's pseudo random number generator does. Even the `Randomize' function will then behave exactly like in BP.
