  - Maybe you could use something like we use here in HP CSY (networking
    lab - OS lab has a bit different setup to my knowledge), where
    we have several build environments (like 4.0, 4.5, 5.0 pull/push).
    Compile/link scripts set up the proper account name to use for includes
    etc, *and* for compiles and linkedit.  Even when the source may be the
    same for all OS versions, the list of include files, defined types,
    compilers and linkedit may have tricks that need to be executed bit
    differently from release to release.
 
    For example, here's a list of SYS-accounts on a system that I use for
    building NS stuff for different OS'es.
 
       SYS        <<-- the 'real' one
       SYS22      '2.2'
       SYS30      '3.0'
       SYS31      '3.1'
       SYS40      '4.0'
       SYS45      '4.5'
       SYS47      '5.0 pull' - some of the early ones
       SYS4718    ...later one
       SYS4720    ...and the final 5.0 pull
       SYS5002    '5.0 push'
       SYS5004    ...next version
       SYS5007    ...next version
       SYS5010    ...MR'd version
 
    Thus the compilers then are as:
 
    PASCALXL.PUB.SYS
    PASCALXL.PUB.SYS22
    PASCALXL.PUB.SYS30
    PASCALXL.PUB.SYS31
    PASCALXL.PUB.SYS40
    PASCALXL.PUB.SYS45
    PASCALXL.PUB.SYS47
    PASCALXL.PUB.SYS4718
    PASCALXL.PUB.SYS4720
    PASCALXL.PUB.SYS5002
    PASCALXL.PUB.SYS5004
    PASCALXL.PUB.SYS5007
    PASCALXL.PUB.SYS5010
