Re: Symbol reference not detected in ARM assembly file

[Shigio YAMAGUCHI]

Hello,
Would you please show the source code which brings the problem?
References to external sites are not desirable in the mailing list,
because they will not necessarily exist tomorrow.

I would like to put this problem to 'Kown bugs'
(http://www.gnu.org/software/global/bugs.html).

Thank you in advance.
