The answer to the question is that the name of the source file ends in 
.F - which indicated the source code will be pre-processed.  The line in 
question uses string concatenation ("//") - which begins an in-line 
comment in C/C++.  So the pre-processor is trimming off a portion of the 
line before gfortran ever sees it.
