+ ;; The 'DEFAULTPATH' string literal, which
+ ;; contains the output path, only appears as
+ ;; the operand of one 'strcpy' call. As a
+ ;; consequence, GCC does not store the string
+ ;; literal as is but instead introduces "gaps"
+ ;; for alignment reasons presumably---like
+ ;; "/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.
