Hi

I am using the sources from cygwin sites.The sources i am using are the l=
atest and the same version of binaries i have installed. I have explained=
 what i have done.
I am configuring for i586 PC running windows.

The directory structure is as follows.
	binutils-20010425-2
	gcc-2.95.3-5
	build
	exe
I create symbolic links for gas,ld,bfd,opcodes,binutils and gprof in the =
main directory of gcc - gcc-2.95.3.5.
Then i run the configure script of gcc in the build directory.When the di=
rectory opcodes is being configured, the configure throws an error saying=
 "ltconfig" doesn't recognise the option "--build".
So configuration of libtool failed.
Then in the configure scripts of all the directories for which i created =
symbolic links i removed the option
"--build" from the options of ltconfig. Then the configuration was  done =
without any errors. =


Then i run "make bootstrap" in the build directory. When compiling the fi=
les in the bfd directory it looks for files in the include directory	of g=
cc. The files it looks for are not in gcc-2.95.3-5/include but are
in binutils-20010425-2/include. So i copied those files from binuitls to =
gcc. Now that problem was solved. Then it gave an error saying in file sy=
sdep.h no rule to make "libintl.h". Then i created a symbolic link for di=
rectory binutils-20010425/intl in the gcc-2.95.3-5 and reconfigured.Then =
i repeated "make bootstrap".
Now it fails  while creating "objdump.exe" saying undefined reference to =
a function "cplus_demangle_name_to_style" and "cplus_demangle_set_style".=


These functions are in the cplus-dem.c file of libeberty of binutils but =
not in libiberty of gcc. These functions are not there in sources from GN=
U GCC sites.

Can u help me on this.

thanking in advance
Deepak
