As of 6f5b06032eb ("Finish gimple_build API enhancement") gimple-fold.h
uses some of the declarations from gimple-iterator.h, which causes
issues when building Linux's stackprotector plugin.
gcc/ChangeLog:
* gimple-fold.h: Add gimple-iterator.h include.

I'm not sure if this should instead be fixed in Linux by reordering the
includes along the lines of

but I figured it was slightly easier for users to keep these compatible.
It looks like many GCC-internal uses of gimple-fold.h already have the
gimple-iterator.h include right before, though, so not sure if that's
how things are meant to be.
