The first time I heard about prefixing struct members was to allow
tricks like this:

x86\_64-linux-gnu/bits/stat.h
94:# define st\_atime st\_atim.tv\_sec /\* Backward compatibility. \*/
95:# define st\_mtime st\_mtim.tv\_sec
96:# define st\_ctime st\_ctim.tv\_sec

Which is relatively safe thanks to the prefix.

Believe me that is not why the prefix convention was introduced.
