it
Patch to suppress all -Wuse-after-free instances.

The attached patch suppresses all instances of the warning at the strictest
setting (-Wuse-after-free=3D3), which includes even uses in equality expres=
sions.
 The default setting approved for GCC 12 is -Wuse-after-free=3D2, which doe=
sn't
warn on such uses to accommodate the pointer-adjustment-after-realloc idiom=
.=20
At the default setting, the changes to ldconfig.c and setenv are not necess=
ary.
