[svn-r11638] Purpose:
Bug fix.

Description:
PGI v6.0-5 pgf90 compiler has a bug in Mstandard that caused compiling
of legal logical value to fail.
We also have second thought of imposing -Mstandard and -Mdclchk on users
since these flags are included in h5fc.

Solution:
Removed -Mstandard until we can fix the v6.0-5 compiler error
and moved -Mdclchk to DEBUG_FFLAGS so that it is used during development
mode but not imposed on users for production release.

Platforms tested:
heping: production and development mode using v6.0-4 compiler.
mir: production and development mode using v6.0-4 compiler.
