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.

libiberty:
* pex-unix.c (pex_unix_wait): Change return type to pid_t.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
