v8 v9 49 49 == Compiler versions == 50 50 51 GHC must be compilable by every major version of GHC from 5.02 onwards, and itself. It isn't necessary for it to be compilable by every intermediate development version (that includes last week's CVSsources). 51 GHC must be compilable by every major version of GHC from sources). 52 52 53 53 To maintain compatibility, use [wiki:Commentary/CodingStyle#HsVersions.h HsVersions.h] (see below) where possible, and try to avoid using #ifdef in the source itself.
