What works:

```
#configure.ac
AC_INIT([helloworld], [0.1], [[email protected]])
AC_MSG_NOTICE([Testing Notify])
AC_OUTPUT
```

What does not work:

```
#configure.ac
AC_INIT([helloworld], [0.1], [[email protected]])
AX_PTHREAD([],[AC_MSG_NOTICE([AC_PACKAGE_NAME Needs POSIX Threads
(pthread)])])
AC_OUTPUT
```

Error:

```
AC_INIT([helloworld], [0.1], [[email protected]])
AX_PTHREAD([],[AC_MSG_NOTICE([AC_PACKAGE_NAME Needs POSIX Threads
(pthread)])])
AC_OUTPUT
```

Happens with `AC_MSG_ERROR` as well.

Tested on current master:

```
commit: cf8b90f6ff221a59a4c625b6f6c41b84c14ee1b9
        Support for the Algol 68 language
```

Tested on a Debian chroot (debootstrap) runing on Fedora host on x86_64

```
OS: Debian GNU/Linux 13 (trixie) x86_64
Kernel: Linux 6.17.7-200.fc42.x86_64
```
