--- Comment #1 from simon at pushface dot org --- Further: $ GNAT_FILE_NAME_CASE_SENSITIVE=1 gnatmake -c p*.ads gcc -c páck3.ads páck3.ads:1:10: warning: file name does not match unit name, should be "páck3.ads" The reason for this apparently-bizarre message is[1] that macOS takes the composed form (lowercase a acute) and converts it under the hood to what HFS+ insists on, the fully decomposed form (lowercase a, combining acute); thus the names are actually different even though they _look_ the same. I have to say that, great as it would be to have this fixed, the changes required would be extensive, and I can’t see that anyone would think it worth the trouble. The recommendation would be "don’t use international characters in the names of library units". [1] https://stackoverflow.com/a/6153713/40851
