It would seem to me that this should be easily accomplished by wrapping
open()/fopen() with code that does some sort of glyph recoding for uppercase
characters.  Getting the library code to access your wrapper would be a minor
macro issue.

While this may not be the answer you were originally looking for, it should
allow you to leave the original code alone, allowing easier rebuilds from
source changes on the original build platforms.
