Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      I wonder how many total person-years of time has been wasted debugging errors arising from implicit int conversions in C.

      Or from porting software to 64 bits and debugging errors due to 'long' doubling its size.

      One legacy codebase had extern prototypes missing in some places. Pointers getting sign-extended are quite a sign, I should say

      would be nice if more compilers actually enforced the missing-prototypes thing (GCC has an option for this, MSVC doesn't do it at all, ...).

      There's no easy solution when migrating legacy code from another compiler and platform because" fixing" any warning can break everything

      This warning is _always_ a serious bug. It should just be an error.

          -Werror=implicit-function-declaration should be a default, damnit.

          Is it not with -std=c99 and -std=c11, the latter of which is default for recent GCC and Clang?

          I guess my brain auto-promotes that warning to an error. I'd use -Werror more but too many m4 scripts aren't ISO 😡

          Another grey hair:VxWorks BOOLEAN is int.The code used BOOLEAN as loop index!Porting layer defined BOOLEAN as bool.Increment optimized out.

          Of course eventually we fixed everything. Just wanted to point out that the first builds that compiled revealed shocking stuff
