[Bug bootstrap/31746] Broken ./configure sed scripting affecting "*gcc/configargs.h" construction.

["rob1weld at aol dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #3 from rob1weld at aol dot com  2007-04-29 18:19 -------
The problem seems to be that the ./configure script is including
"--enable-languages" TWO times and the second time it is NOT quoting it - thus
breaking sed.

My ./configure command line (I use a shell script, I don't type it in :) ) is:

/root/downloads/gcc-4_2-branch/configure --verbose
--enable-languages=c,ada,c++,fortran,java,objc,obj-c++ --with-tune=athlon-xp
--prefix=/usr --enable-objc-gc --enable-concept-checks --disable-multilib
--with-gxx-include-dir=/usr/include/c++/4.2 --enable-libstdcxx-debug
--enable-static --enable-shared --enable-initfini-array --enable-__cxa_atexit
--enable-threads=posix --enable-version-specific-runtime-libs --enable-libssp
--enable-libmudflap --enable-libgomp --disable-werror --enable-nls
--with-included-gettext --enable-decimal-float --with-long-double-128
--enable-debug --disable-sjlj-exceptions --enable-java-gc=boehm --with-x
--x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
--enable-java-awt=gtk,xlib --enable-gtk-cairo --enable-qt-peer --enable-xmlj
--enable-gconf-peer --enable-tool-wrappers --with-gjdoc
--enable-portable-native-sync --enable-libgcj-multifile --with-stabs
--enable-hash-synchronization --enable-gc-debug --enable-interpreter
--with-system-zlib --enable-libada --with-tls --with-cpu=athlon-xp
--with-arch=athlon-xp --enable-checking

Note I only specify "--enable-languages=c,ada,c++,fortran,java,objc,obj-c++" a
_single_ time, but even if I did specify it ten times the *_configargs=XYZ"
should only show it once and it should be single quoted.

Perhaps our shells are different and yours is not affected. I compile through a
X11 window - here is my xterm and bash versions (for Linux both are "apt-get"
recent, for Cygwin both are Setup.exe recently updated):


For gnu/Linux (Debian):

/opt/gcc-4_2-build# xterm -version
XTerm(222)
/opt/gcc-4_2-build# bash --version
GNU bash, version 3.1.17(1)-release (i486-pc-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.
/opt/gcc-4_2-build# 


For WinXP (Cygwin):

$ xterm -version
Cygwin 6.8.2.0(202)

$ bash --version
GNU bash, version 3.2.15(13)-release (i686-pc-cygwin)
Copyright (C) 2005 Free Software Foundation, Inc.


My X11 is:
$ x --version
Welcome to the XWin X Server
Vendor: The Cygwin/X Project
Release: 6.8.99.901-4

My window-manager is OpenBox. This problem poped up in the last month. I tried
to not complain and see if it would be fixed after a few updates - but like you
said, some other people don't have this problem. It is NOT a "visible" problem
unless you type "gcc -v". The compiler works fine with this error.
