/**
 * @file pcre2.c
 * @brief PCRE2 configuration header and includes for regex-related opcodes.
 *
 * Ensures PCRE2 code unit width is defined consistently prior to including
 * <pcre2.h> when FUN_WITH_PCRE2 is enabled.
 */
 
/* Ensure PCRE2 is configured consistently across the whole translation unit.
 * vm.c includes many opcode implementation .c files; some use PCRE2. For PCRE2
 * headers to expose the correct typedefs (e.g., pcre2_code, PCRE2_SPTR), the
 * PCRE2_CODE_UNIT_WIDTH macro must be defined before the first inclusion of
 * <pcre2.h>. We do this once here when PCRE2 support is enabled. */
