Addresses #215

Looks good to me.

Pound it.

please use #pragma gcc instead of #pragma clang. this is compatible with both compilers

[alanking]

I was wondering about that. Will update

[alanking]

#pragma clang replaced with #pragma gcc for lines affected by this PR as well as a couple of others I found elsewhere in the codebase (separated for visibility). There's one in the third-party directory which I did not touch:

$ grep -nrI "pragma clang diagnostic ignored"
third-party/date/include/date/tz.h:64:# pragma clang diagnostic ignored "-Wconstant-logical-operand

[alanking]

Whoops, should be #pragma GCC, not #pragma gcc: https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Pragmas.html

Fixed.

Code has changed since last review.

[korydraughn]

Changes look fine.

Please re-run that one failed GHA to get the green dot and we'll get this in.

[alanking]

Green now

[korydraughn]

Squash to taste.

[alanking]

Squashed

[korydraughn]

Pound it.
