Bug ID: 71850
   Summary: CreateProcess argumend lpCommandLine exceeds limit 32k
limit
   Product: gcc
   Version: 6.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: driver
  Assignee: unassigned at gcc dot gnu.org
  Reporter: christian.wilmes at elektrobit dot com
  Target Milestone: ---

Under windows the command line is limited to 32k. When passing an compiler
option file (via @optionfile) it is parsed by gcc and then a call to cc1 is
generated via CreateProcess API. In this case gcc passes the parameters from
the option file and does not check wether it exceeds the 32k limit. For example
if someone defines too many include directories gcc will crash with a
"CreateProcess: No such file or directory" error.

[Bug driver/71850] @file should be used to cc1/cc1plus when @file is used
