The recent warning patches broke Solaris bootstrap:
/vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: error: initialization
of 'pid_t (*)(struct pex_obj *, pid_t, int *, struct pex_time *, int, const
char **, int *)' {aka 'long int (*)(struct pex_obj *, long int, int *, struct
pex_time *, int, const char **, int *)'} from incompatible pointer type 'int
(*)(struct pex_obj *, pid_t, int *, struct pex_time *, int, const char **,
int *)' {aka 'int (*)(struct pex_obj *, long int, int *, struct pex_time *,
int, const char **, int *)'} [-Wincompatible-pointer-types]
326 | pex_unix_wait,
| ^~~~~~~~~~~~~
/vol/gcc/src/hg/master/local/libiberty/pex-unix.c:326:3: note: (near
initialization for 'funcs.wait')
While pex_funcs.wait expects a function returning pid_t, pex_unix_wait
currently returns int. However, on Solaris pid_t is long for 32-bit,
but int for 64-bit.
This patches fixes this by having pex_unix_wait return pid_t as
expected, and like every other variant already does.
Bootstrapped without regressions on i386-pc-solaris2.11,
sparc-sun-solaris2.11, x86_64-pc-linux-gnu, and
x86_64-apple-darwin23.1.0.
Ok for trunk?
