Doxygen does not correctly parse the '\' character in FORTRAN code. For example, the Doxygen html output of the source code displays incorrect line numbers and colouring.

IF ( c(i:i).EQ.'/' .OR. c(i:i).EQ.'\' ) THEN
 Dir_Len = i
END IF 

I actually could fix this problem by doing this

CHARACTER BKSLASH*2
BKSLASH='\\'
IF ( c(i:i).EQ.'/' .OR. c(i:i).EQ.BKSLASH(1:1) ) THEN
 Dir_Len = i
END IF

I think this is due to the fact that Doxygen was desigend to parse C/C++ programs, where the '\' character is used as a escape sequence. But in F77/F90 this is not the case. But hats off to the folks for adding FORTRAN support to Doxygen. You have done a great work.
