--- Comment #17 from Thomas Wolff <towo at towo dot net> ---
This is getting picky. I wouldn't say there's double quoting involved.
The string given to the -preprocessor arguments seems to be simply fed into a
call of popen(), and that should be fine. It may contain quotes as needed.
Quoting the whole argument again in the shell is not really double-quoting in
this sense.
So "\"path to gcc\" arguments..." is neither a trick nor anything special to
remember, it's normal syntax in such use cases.
Whether the wrong commit was reverted or not I cannot judge right now, I was
only asking to restore the 2.35 behaviour which is consistent with general
POSIX string handling and which supports everything anyone needs. Breaking such
support after years is what's generally called a regression and it's generally
and rightfully frowned upon.
