commit r17-2633-gf128c347d5278a521f8101a4a237493a25e6f143 Author: James K. Lowden <[email protected]> Date: Wed Jul 22 18:16:43 2026 -0400 cobol: Restrict CDF reserved words to CDF parsing. Among others PARAMETER was captured as a reserved word during normal parsing, which it is not. Move that and some other obvious CDF tokens to the cdf_state start condition. gcc/cobol/ChangeLog: * scan.l: Make PARAMETER and friends unspecial outside CDF.
