[patch ld]: deffilep.y needs support for leading dots for symbol names

[patch ld]: deffilep.y needs support for leading dots for symbol names

[-- Attachment #1: Type: text/plain, Size: 665 bytes --]

Hello,

this patch addresses the case that for x64 (without leading
underscores and I assume the same can happen for arm), that a symbol
gets prefixed by a dot. At the moment our deffilep parser doesn't
supported this. See also for this
http://sourceware.org/bugzilla/show_bug.cgi?id=11612.

ChangeLog

2010-05-19  Kai Tietz

        * deffilep.y (opt_name): Allow leading dot.
        (dot_name): Likewise.
        (anylang_id): Likewise.

Patch tested for x86_64-pc-mingw32, i686-pc-mingw32, and
i686-pc-cygwin. Ok for apply?

Regards,
Kai
