/*
 * SCWS prior to 1.2.3 declared a function named `pstrdup` in scws.h, which
 * collides with PostgreSQL's pstrdup() macro. Rather than #define-shadowing
 * it (which is fragile if SCWS later inlines or changes the signature), we
 * isolate the rename to this header only.
 *
 * Build systems linking against SCWS >= 1.2.3 can pass
 * -DZHPARSER_SCWS_HAS_NO_PSTRDUP_CONFLICT to skip this entirely.
