<p dir="auto" style="color: #303030; margin: 0 0 16px;" align="initial">This suggests the symbol is local (denoted by the lowercase s). <code style='font-size: 90%; color: #1f1f1f; word-wrap: break-word; background-color: #f0f0f0; border-radius: 4px; margin-top: 0; font-weight: inherit; font-family: "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>nmedit -s</code> then fails because it expects <code style='font-size: 90%; color: #1f1f1f; word-wrap: break-word; background-color: #f0f0f0; border-radius: 4px; font-weight: inherit; font-family: "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>__gnutls_x86_cpuid_s</code> to be global.
