Which parts of termbox2.h are not C99 compliant? What compiler doesn't "ignore" the non-C99 compliant code when -std=c99 is passed? I maintain my own simple editor called sled[1], which uses termbox2.h and passes `-std=c99` as a default flag. I have compiled it using GCC, Clang/LLVM, tinycc, on (GNU/)Linux and OpenBSD, and I have yet to encounter any errors. I tried compiling your program using `CC=c99` (script wrapper to GCC) and passing `-std=c99`, and there are only some warnings about implicitly declared functions, nothing about `struct sigaction`. In any case, you can simply include the needed headers prior to including termbox2.h (my program uses signal.h to redraw after C-Z, so I include it anyway). [1]: https://strahinja.srht.site/sled/
