I agree with you, at least largely.
Redefining functions, be it by linking in something or by redefining function
names via macros, is a mess. There's places where we then have to undefine
some of these things to be able to include external headers etc. Some
functions are only replaced in backends, others in frontend too. It makes it
hard to know what exactly the assumed set of platform primitives is. Etc.
