Update DEC compiler support

Description:
    Updated DEC/Compaq compiler detection to handle DEC->Compaq switchover
in compiler version string.

    Also, copied v5.x compiler flags to V6.x compiler flags and included the
-ieee and -misalign flags necessary for correct floating-point support.

Platforms tested:
    Pittsburgh Alpha Cluster (lemieux.psc.edu)
