It appears someone (un)fixed your changed.

mobile:kargl[214] grep gfc_show_expr *c
mobile:kargl[215] grep -2 -E ^show_expr *c
dump-parse-tree.c-
dump-parse-tree.c-static void
dump-parse-tree.c:show_expr (gfc_expr *p)
dump-parse-tree.c-{

Checking ChangeLog, no one appears to own up to this change.
