[jed-users] Weird warning & results in JED compilation

[Nicholas Christopoulos <nereus@xxxxxxxxxxx>]

This weird warning shown when compiling (original) JED with default
options (-g -O2)

```
In function 'get_full_popup_name',
    inlined from 'run_popup_callback' at
/lanfs/src/jed/src/menu.c:1529:24: /lanfs/src/jed/src/menu.c:1518:2:
warning: 'strncpy' specified bound depends on the length of the source
argument [-Wstringop-overflow=] 1518 |  strncpy (s, parent->name, len);
|  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /lanfs/src/jed/src/menu.c: In
function 'run_popup_callback': /lanfs/src/jed/src/menu.c:1516:8: note:
length computed here 1516 |  len = strlen (parent->name);
      |        ^~~~~~~~~~~~~~~~~~~~~
```

I had some unexplained results in my patched code that added to
original source. I lost one day huntings ghosts until I found something
wrong was with default GCC optization.

Example:
```
void f(int x) {
syslog(0, "JED FLAG: %08X\n", x); // outputs 2!
}
...
x = 6;
f(x);
```

Both issues solved by adding in first lines of menu.c
#pragma GCC optimize("-O0")
which means do not optimize this module.

I would try to expain nothing... I had to report it and I did it.
