This broke in CI but not on my local machine because of the different
compiler version. This is because there was an issue in GCC [1] that
caused the attribute to not properly work on multidimensional arrays.
This has since been fixed in GCC 15.
Therefore, we guard the attribute with a version check.

Starting with gcc 15 the warning `-Wunterminated-string-initialization`
is enabled by default. We make now use of the `nonstring` attribute to
silence the warning for the cases where this is intended.
Closes GH-18603.
Make data_file.c's generator output its array initialization
"by list of strings", instead of "by list of chars": that makes the compiler
happier.
Use strtr() with a precomputed map, instead of a loop over ord(),
to generate in 1/100th the time.
Avoids ambiguous 0x tokens (as specified in C standards), by using octal.
Closes GH-10422.
This patch makes few remaining PHP development tools files
executable and adds a shebang to them.
The `#!/usr/bin/env php` shebang provides running the script via
`./script.php` and uses env to find PHP script location on the system.
At the same time it still provides running the script with a user
defined PHP location using `php script.php`. Shebang is not visible in
the output of the generated file.
