[Bug fortran/34997] New: Common vendor extension: Support symbol names containing $

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This seems to be a common vendor extension. Example:

      REAL*4 PLT$C_HOUSTPIX
      INTEGER PLT$C_COMMAND
      PARAMETER (PLT$B_OPC=0)
      common /abc$def/ PLT$C_HOUSTPIX, PLT$C_COMMAND
      end

This compiles using NAG f95 (with the warning "Extension: Name contains $
character") and with ifort, sunf95, openf95. With "-stand f95" also ifort warns
("Invalid use of $ character in identifier"). While gfortran rejects it
completely (syntax error).
