How about something like this:
#if PCRE_LIBRAY_SUPPORTS_BOTH_EBCIDC_AND_UNICODE
#define CHAR_LEFT_SQUARE_BRACKET (context->usingEbcdic ? EBCDIC_LEFT_SQUARE_BRACKET : '[')
#elif PCRE_LIBRAY_SUPPORTS_ONLY_EBCDIC
#define CHAR_LEFT_SQUARE_BRACKET (EBCDIC_LEFT_SQUARE_BRACKET)
#else
#define CHAR_LEFT_SQUARE_BRACKET '['
#endif
I don't have any use for EBCDIC myself, but evidently some people do, and it's probably worthwhile in the long run to support a layer of abstraction rather than hard-code the characters at a low level.
