The following Fortran 77 program declares and uses a statement function
I2C(M). When compiled with these options:
g77 -pedantic -v -save-temps
it is misread as a character substring with its : missing, but IMHO
this statement function is valid in Fortran 77. The program compiles
and runs OK if the -pedantic is removed. Below are the program listing,
the compiler output, and the .s file generated by the compiler.
There was no .i* file.
tahi[~/Jfh] % cat testsf.f
PROGRAM TESTSF
CHARACTER I2C*2, CDIGIT(0:9)*1
DATA CDIGIT/'0','1','2','3','4','5','6','7','8','9'/
* Statement function I2C to convert integer 0 to 99 to character*2
I2C(M) = CDIGIT(M/10) // CDIGIT(MOD(M,10))
* End of statement functions; start of executables
PRINT '(10A3)', (I2C(M),M=0,99)
END

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-03-06 22:56 -------
Fixed in 4.0.0 with the gfortran rewrite. 3.4.6 is about to be released and
there is almost no way to get a non regression fixed.
So closing as fixed for 4.0.0.
