- ;; The 'DEFAULTPATH' string literal, which

- ;; the operand of one 'strcpy' call. As a
- ;; consequence, GCC does not store the string
- ;; literal as is but instead introduces "gaps"

- ;; "/gnu/sto?????re/8jp8b??????ky105…". This
- ;; makes this string invisible to the GC, which
- ;; in turns causes problems when running a
- ;; grafted WordNet because that grafted WordNet
- ;; keeps referring to the ungrafted variant,
- ;; which is not protected from GC. Thus,
- ;; disable use of '__builtin_strcpy' to avoid
- ;; that.
