test/t51_gvar_linkage_upgrade.nsc

/* regression test, gvar half of the same jscope2 bug the include test
 * covers for functions: a bare (non-global, no-initializer)
 * reference to a name, followed later by its real `global`
 * definition, must upgrade linkage to global -- previously the
 * upgrade only ever happened in the has-an-initializer case, so a
 * bare-reference-then-tentative-global-definition (exactly what a
 * shared header full of plain declarations plus one file's own
 * `global` definition produces) silently stayed 'local' forever. */
