syntax error on 4.9.2

[Mahmood Naderan]

Hi
I am running the following command to compile a fortran code

    gfortran -ffree-form -ffree-line-length-0 -ff2c
-fno-second-underscore -I/opt/fftw-3.3.5/include -O3 -c xml.f90
-I/opt/openmpi-2.0.1/include -pthread -I/opt/openmpi-2.0.1/lib
    xml.F:641.46:

           CALL XML_TAG("set", comment="spin "
                                              1
    Error: Syntax error in argument list at (1)


That line is

    CALL XML_TAG("set", comment="spin "//TRIM(ADJUSTL(strcounter)))

It seems that the code is compatible fortran. I don't know which
version, but currently, gfortran is 4.9.2 (ubuntu 15.04). How can I
fix that?

Regards,
Mahmood
