I don't think it *should* be generated at build time (the only thing that 
needs ulps information at build time should be the table in the manual), 
but don't know offhand what dependency is causing it to be generated 
early.  Also, even if generated early, it ought not to break regen-ulps 
for the header to be already present - so that sounds like a makefile 
issue as well.
