Proposed patch - but without test
On macOS I get
$ echo '#include "/Users/Axel/Tmp/T.h"' | clang -cc1 -x c++ -E -
# 1 "<stdin>"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 320 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "<stdin>" 2
<stdin>:1:10: warning: non-portable path to file '"/UUsersAaxelTtmpTT.h"';
specified path differs in case from file name on disk
#include "/Users/Axel/Tmp/T.h"
^~~~~~~~~~~~~~~~~~~~~
"/UUsersAaxelTtmpTT.h"
# 1 "/Users/Axel/Tmp/T.h" 1
# 2 "<stdin>" 2
1 warning generated.
due to an off-by-one error for absolute paths. Attached patch seems to fixe
that.
I'd commit myself but I don't know how to write a test for that :-( Sorry!
Axel.
