I knew about the double-underscore, but somehow missed
single-underscore-followed-by-capital letter.

I think if we were to follow this rule – which nobody else seems to do
– that we'd also have to change all our:

struct _Foo {};
typedef struct _Foo Foo

stuff to avoid the _F. I say we ignore it and on the off chance glibc
tries to define a _PURPLE_ACCOUNT macro, we'll worry about it then.
