Message:

/Config.kmk,webservices: Apply -fno-printf-return-value to try prevent potential internal compiler errors in some GCC versions (9.x). The -fprintf-return-value optimization pass isn't helpful for us anyway, because the code isn't doing any sprintf or similar calls I can see, and when printf'ing anything it (void) the return.
