libpng
contrib/libtests/pngvalid.c calls feenableexcept(), a glibc extension
relibc does not provide, and GCC 14+ makes the implicit declaration an
error. It is a test program, so build it the way AGENTS.md
§ CONVENTIONS already prescribes for cross builds -- '--disable-tests'.
The library is unaffected; only check_PROGRAMS is skipped, and those
binaries cannot run on the build host regardless.
zsh
zsh 5.9 probes for the termcap symbol arrays with
char **test = boolcodes; puts(*test);
and ncurses declares boolcodes as 'const char * const *'. GCC 14
promoted -Wincompatible-pointer-types to an error, so the probe stopped
compiling, configure concluded boolcodes=no, HAVE_BOOLCODES was left
undefined, and Src/Modules/termcap.c fell back to defining its own
array -- colliding with the header:
termcap.c:45: error: conflicting types for 'boolcodes'
The probe uses a bare shell variable, not an ac_cv_ cache entry, so
there is nothing to override; restoring the pre-GCC-14 severity is what
lets it reach the right answer. Scoped to this recipe so the rest of the
tree keeps the stricter default.
Both cook clean.
