Summary

0005312: windows, @responsefile and warnings-as-errors

Description

I have software that uses new syntax of ocamlc command
line, "-w @a" (enable all warnings and treat them as
errors), but function "expand_argument" in
"byterun/win32.c" tries to expand "@a" as a filename:

> ocaml -w @a
Cannot open file a

As the @responsefile functionality is not widely used
anymore, I have fixed it locally and have not
experienced any trouble. I don't know whether
this solution is acceptable.

Notes
(0007171) lefessan (developer) 2012-03-26 16:12	Gabriel, we agreed that it is time to remove responsefile from the runtime. Could you do it ?

(0007681) doligez (manager) 2012-07-10 14:01	For the record, you can work around the problem by adding something before the @: ocamlc -w a@a

(0007682) gasche (developer) 2012-07-10 14:05	The feature has now been removed. This means that OCaml programs will not expand command-line arguments beginning with a "@" as responsefiles on Windows anymore, but instead pass them directly to the program (in Sys.argv as usual). All OCaml programs compiled under Windows are affected. This is a change of behavior, but a community poll on the mailing-list indicated that basically no one was aware of this feature. Removing it will therefore protect users from a few surprises if they try, as the OCaml compiler authors, to use "@..." as a valid syntax for specific command-line parameters...
