As reported in PR libsframe/33168, the libsframe tests don't build on
Solaris. The failure is
In file included from libsframe/testsuite/libsframe.decode/be-flipping.c:28:
/usr/include/dejagnu.h:48:1: error: conflicting types for ‘wait’; have ‘void(void)’
48 | wait (void)
| ^~~~
In file included from /usr/include/stdlib.h:16,
from libsframe/testsuite/libsframe.decode/be-flipping.c:21:
/usr/include/sys/wait.h:85:14: note: previous declaration of ‘wait’ with type ‘pid_t(int *)’ {aka ‘long int(int *)’}
85 | extern pid_t wait(int *);
| ^~~~
We have a combination of two factors here:
* Solaris <stdlib.h> has
and configure.ac predefines __EXTENSIONS__ due to the use of
AC_USE_SYSTEM_EXTENSIONS.
* This conflicts with <dejagnu.h>'s definition
void
wait (void)
{
...
}
While this version of wait was removed in upstream DejaGnu, the removal
only happened after the latest release, 1.6.3.
To avoid this, I've moved all testsuite includes into a new
sframe-test.h, adding a workaround for the wait conflict.
-Wall and -I$(srcdir) have been removed from AM_CPPFLAGS since they
don't seem to be needed. To fix the Makefile fragment duplication, the
local.mk files now use $(testsuite_LDADD) and $(testsuite_CPPFLAGS)
throughout.
Tested on {i386,amd64}-pc-solaris2.11, {sparc,sparcv9}-sun-solaris2.11,
{x86_64,i686}-pc-linux-gnu, and amd64-pc-freebsd14.0.
