The configure script now sets the variable GCC_RAW_VERSION which is

parsed in Jamrules into a list (`.' and `-' are considered delimiters)
written into GCC_VERSION. E.g. for the GeekGadgets compiler expect
GCC_VERSION to be set to `2 9 beos 000224'. So, GCC_VERSION[1] should
contain the major version, GCC_VERSION[2] the middle one.
