I met this problem with libICE on NetBSD 4.0_STABLE today.

Has this problem solved?

Original line looks expect $as_echo work as normal echo(1) (Of course,
it isn't portable as for outputing without newline.)

cacheid=`$as_echo xorg_cv_cc_flag_-errwarn=E_NO_EXPLICIT_TYPE_GIVEN 
-errwarn=E_NO_IMPLICIT_DECL_ALLOWED`

Then, $as_echo contains:

printf %s\n

It insert newline after first argument (or first word).

And $as_tr_sh looks not to handle newline.

So, quoting parameter to $as_echo:

cacheid=`$as_echo "xorg_cv_cc_flag_-errwarn=E_NO_EXPLICIT_TYPE_GIVEN 
-errwarn=E_NO_IMPLICIT_DECL_ALLOWED"`

configure successfully completed.

Best regards.
