Code written 20 years ago often won't compile with today's -Wall.
Is there a record of default settings for say GCC from 1997, or other years?
And I know I can turn off individual error/warnings in GCC.

2How about `-ansi`, `-c90` and [similar](https://gcc.gnu.org/onlinedocs/gcc/C-Dialect-Options.html)? – Arkadiusz Drabczyk Apr 26 '17 at 17:12

that might be the only option. But it's hard to tell what standard was used for old code if the source doesn't come with a Makefile or similar; like when there's only a few functions or single isolated source file. – novelistparty Apr 27 '17 at 23:00
