USER_H is GCC's mechanism to disable installing some of the headers, such 
as stddef.h, that it installs by default.  You're meant to set it in a 
target makefile fragment t-* instead of changing the global default 
definition in gcc/Makefile.in.  Thus, if NetBSD should have all the 
GCC-provided headers except for stddef.h, copy the default from 
gcc/Makefile.in to gcc/config/t-netbsd and remove stddef.h there (with a 
comment to say that it's stddef.h that's being removed).
