+@section Common Problems
+
+@subsection Error Message Indicates Invalid Option to Assembler
+
+If a message like this is printed then the new cross compiler
+is most likely using the native assembler instead of the cross
+assembler or vice-versa (native compiler using new cross assembler).
+This can occur for one of the following reasons:
+
+@itemize @bullet
+
+@item Binutils Patch Improperly Applied
+@item Binutils Not Built
+@item Current Directory is in Your PATH
+
+@end itemize
+
+If you are using binutils 2.9.1 or newer with certain older versions of
+gcc, they do not agree on what the name of the newly
+generated cross assembler is. Older binutils called it @code{as.new}
+which became @code{as.new.exe} under Windows. This is not a valid
+file name, so @code{as.new} is now called @code{as-new}. By using the latest
+released tool versions and RTEMS patches, this problem will be avoided.
+
+If binutils did not successfully build the cross assembler, then
+the new cross gcc (@code{xgcc}) used to build the libraries can not
+find it. Make sure the build of the binutils succeeded.
+
+If you include the current directory in your PATH, then there
+is a chance that the native compiler will accidentally use
+the new cross assembler instead of the native one. This usually
+indicates that "." is before the standard system directories
+in your PATH. As a general rule, including "." in your PATH
+is a security risk and should be avoided. Remove "." from
+your PATH.
+
+NOTE: In some environments, it may be difficult to remove "."
+completely from your PATH. In this case, make sure that "."
+is after the system directories containing "as" and "ld".
+
+@subsection Error Messages Indicating Configuration Problems
+
+If you see error messages like the following,
+
+@itemize @bullet
+
+@item cannot configure libiberty
+@item coff-emulation not found
+@item etc.
+
+@end itemize
+
+Then it is likely that one or more of your gnu tools is
+already configured locally in its source tree. You can check
+for this by searching for the @code{config.status} file
+in the various tool source trees. The following command
+does this for the binutils source:
+
+@example
+find @value{BINUTILS-UNTAR} -name config.status -print
+@end example
+
+The solution for this is to execute the command
+@code{make distclean} in each of the GNU tools
+root source directory. This should remove all
+generated files including Makefiles.
+
+This situation usually occurs when you have previously
+built the tool source for some non-RTEMS target. The
+generated configuration specific files are still in
+the source tree and the include path specified during
+the RTEMS build accidentally picks up the previous
+configuration. The include path used is something like
+this:
+
+@example
+-I../../@value{BINUTILS-UNTAR}/gcc -I/@value{BINUTILS-UNTAR}/gcc/include -I.
+@end example
+
+Note that the tool source directory is searched before the
+build directory.
+
+This situation can be avoided entirely by never using
+the source tree as the build directory -- even for
+
