C preprocessor: #pragma push_macro / pop_macro

• Type: feature (cpreproc). Track C. Small.
• Found: 2026-07-06 c-testsuite run.

Failing test

• 00206: #pragma push_macro("abort") / pop_macro save/restore macro definitions (stack per name). We ignore the pragma → last #define sticks (prints 333/333 instead of 222/111 after pops). Also: a user macro NAMED pop_macro/push_macro must not confuse the pragma.

Gate

Drop 00206.c from test/c-conformance/pxx.skip; runner green.
