/* 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. */
