[fpc-pascal] ifdef'ing FreeBSD by os version number

[Marc Santhoff]

Hi,

are there flags defined in the fpc sources for discriminating different
os versions?

While translating some structures from the systems USB headers I found
changes, some fields added and the like. This needs to be reflected in
the translation.

Version in question are FreeBSD4, 6 and 7 currently.

TIA,
