pen.c:277: redefinition of `struct statfs'
pen.c: In function `vfs2fs':
pen.c:367: structure has no member named `val'
pen.c:370: structure has no member named `f_basetype'
*** Error code 1

I was using bootstrap-pkgsrc from a couple months ago. The difference then
was:
-#ifdef HAVE_STATVFS
+#ifndef HAVE_STATVFS
