In my code, I occasionally use recursive macros as helpers to generate boiler-plate code. If a compiler error occurs in some code generated by the macro, I get something like the following:

...
Where the above "in expansion of" notes are repeated dozens of times.
Since this information is completely useless in actually determining the source of the problem (I only need the first few lines) does anyone know if it is possible to suppress these notes in GCC?
I am using GCC 8.2.0 (MinGW.org GCC-8.2.0-3)
