I know.

I would argue it's a "false positive": the header generate.hpp is a 
maintenance header used for generating new numeric constants, and the 
dependency to multiprecision is optional (inside #ifdef's).  It is 
however documented, so I'm loathed to just move it.  There are quite a 
few of Math's dependencies that are introduced via similar headers that 
exist for maintenance/testing/optional use, and are not included by any 
of the "include everything" entry point headers.
