I wonder if it would not be better to do the conformance checking in 
trans-intrinsic.c(gfc_conv_intrinsic_function_call) itself; or in a 
subsidiary function?

The reason that I suggest this is that it avoids any modifications to 
the library, either by adding a conformance check flag to the arguments 
or by doubling up of the library functions.

It should be easy enough to write a function that generates code to 
check the shapes of arrays - in fact, I volunteer to do it myself :-)

Best regards
