error: ‘size_t’ undeclared (first use in this function)

libdjvulibre-dev 3.5.23-3 on Ubuntu 11.04

I tried to build zathura-djvu plugin which depends on djvulibre and get this error:

Why could this be?

It may have something to do with not explicitly including stddef.h in miniexp.h: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625073

Yes, that's right and apparently fixed in 3.5.25.
Changing miniexp.h appropriately solves this issue
