Silence the warning: `Non-conforming tab character` in gfortran

Question

I usually run my code with ifort, but during implementation, I prefer compiling and testing with gfortran as I find it to be a lot stricter than its intel counterpart.

While turning on compiling options such as -Wall, I get the following warning:

Warning: Nonconforming tab character at (1)

Is there a way to silence this one particular warning while using the same compiling options? Note that I do NOT want to replace tabs with space characters. If there is no way to resolve this issue, then the answer "No it's not possible" would suffice.

Answer 1

UPDATE: With GCC/gFortran 5xx (I noticed with 5.3.0), the -Wtabs usage has been "reversed", and as they say, "made more sensible".

See here (https://gcc.gnu.org/gcc-5/changes.html)

Now -Wtabs DOES give the nonconforming warning, whereas -Wno-tabs TURNS OFF the warning (i.e. the opposite of the previous usage).
