[Bug fortran/23254] New: gfortran .f90 complex parameter initialization syntax bug

["christopherbuell at mindspring dot com" <gcc-bugzilla at gcc dot gnu dot org>]

While testing some FORTRAN 90 code under Fedora Core 4,
I found problem initializing COMPLEX PARAMETERs with other
parameters that have + or - in front of the variable name.

The following .f90 test code will illustrate the problem.
All lines should compile fine.
The lines that fail are commented with "fail"

module consts_test

  real(8), parameter :: konst1 = 1.0d0

  complex, parameter :: const1 = (1.0d0,1.0d0)        ! good
  complex, parameter :: const2 = (1.0d0,-1.0d0)       ! good
  complex, parameter :: const3 = (-1.0d0,-1.0d0)      ! good
  complex, parameter :: const4 = (-1.0d0,1.0d0)       ! good
  complex, parameter :: const5 = (+1.0d0,+1.0d0)      ! good
  complex, parameter :: const6 = (konst1,konst1)      ! good
  complex, parameter :: const7 = (konst1,-konst1)     ! fail
  complex, parameter :: const8 = (-konst1,-konst1)    ! fail
  complex, parameter :: const9 = (-konst1,konst1)     ! fail
  complex, parameter :: const10 = (+konst1,+konst1)   ! fail

end module consts_test
