The "string constant" on a #-line is interpreted the same way as a
double-quote include, i.e. \ escapes are *not* interpreted.  Try your
test again with -S -save-temps, you will see that the proper .file
string appears in the assembly output.

I do not see what else you could mean by "mishandles \ in filenames."
Please clarify.
