Sorry for delay.
I've downloaded binutils-2.21.51
[binutils]$ grep 201104 binutils-2.21.51/ -r
binutils-2.21.51/bfd/version.h:#define BFD_VERSION_DATE 20110416
It contains your changes related to bool map_is_allocated_;

It is still having the problems I've mentioned earlier(in my patches):
build/binutils-2.21.51/gold/descriptors.cc:136: error: 'F_SETFD' was not declared in this 
scope
build/binutils-2.21.51/gold/descriptors.cc:136: error: 'fcntl' was not declared in this scope
build/binutils-2.21.51/gold/output.cc:4552: error: 'S_ISLNK' was not declared in this scope

Chunks fixing the issues are attached.

I'll let you know about new gold work in a day or so.

Best regards
