Summary: winegcc does not properly pass cmdline args, e.g.
                    -Wb,--as-cmd="as --32"
           Product: Wine
           Version: 1.3.2
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: build-env
        AssignedTo: wine-bugs@winehq.org
        ReportedBy: armin.kazmi@tu-dortmund.de
When trying to build a simple test.c file with winegcc, winegcc fails to
properly pass over commandline arguments to winebuild.
test.c only contains an emtpy main function. In practise this error was
verified with the vst plugin of lmms.
Test cmdline: 
winegcc test.c -o test -m32 -Wb,--as-cmd="as --32",--ld-cmd="ld -melf_i386"
Resulting output:
winebuild: as --32 failed with status 1
winegcc: winebuild failed
Another testcase
Cmdline:
winegcc test.c -o test -m32 -Wb,--as-cmd="as ",--ld-cmd="ld "
Output:
winebuild: as  failed with status 1
winegcc: winebuild failed
Running the same first cmdline with the -v option reveals the error:
winegcc test.c -o test -m32 -Wb,--as-cmd="as --32",--ld-cmd="ld -melf_i386" -v

winegcc: winebuild failed
------
The error lies in $WINESRC/tools/winegcc/winegcc.c lines 1360 and following.
Winegcc assumes that the command line arguments remain quoted as shown in the
cmdline above, but instead winegcc receives the following as 4th arg
"--as-cmd=as --32" (as verified with a simple program just outputting the
args), so actually the quotes get lost and need to be manually filled in if
winegcc starts a script running winebuild. Franky, I don't know too much of the
process used here.
Attached is a chatlog between me and A. Hentschel.
