I tried to build diffutils 3.11 and 3.12 with GCC 14.2, both fail here:

Adding -Wincompatible-pointer-types to turn errors into warning does change the
failure. SIG_DFL is #define'd in sgnal.h:
116 #if defined(_ANSI_SOURCE) || defined(_POSIX_C_SOURCE) ||
defined(__cplusplus)
117 /*
118 * Language spec sez we must list exactly one parameter, even
though we
119 * actually supply three. Ugh!
120 * SIG_HOLD is chosen to avoid KERN_SIG_* values in
<sys/signalvar.h>
121 */
122 #define SIG_DFL (void (*)(int))0
123 #define SIG_IGN (void (*)(int))1
124 #define SIG_HOLD (void (*)(int))5
125 #define SIG_ERR ((void (*)(int))-1)
126 #else
127 /* DO NOT REMOVE THE COMMENTED OUT int: fixincludes needs to
see them */
128 #define SIG_DFL (void (*)(/*int*/))0
129 #define SIG_IGN (void (*)(/*int*/))1
130 #define SIG_HOLD (void (*)(/*int*/))5
131 #define SIG_ERR ((void (*)(/*int*/))-1)
132 #endif
None of _ANSI_SOURCE, _POSIX_C_SOURCE, or __cplusplus are defined by GCC 14.2
here. As an amateur I have no idea how to solve this, so I'm going to live with
the Apple supplied tools.
