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)
