We once did have code to avoid such issues like, however I removed
it.  See commit c5b9ae4e3f5f4037fc3816bcbcec60982734196b,

Reason was that IMO problems because of multiple -I's for the same
path should be fixed in the Makefile/build system, not in the compiler.

Not at least if the compiler is the tiny C compiler.

Say it's just that stuff like "st_ino" or "dwVolumeSerialNumbers" in
this program (that otherwise just uses open/read/write/close, more or less),
doesn't look good.  A matter of taste.  A case of "the feature is not to
have that feature".  Which you might or might not agree to ;)
