Possibly revisit workaround(s)

[sum01]

Workaround bug in gcc 4.7: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52680

This workaround was fixed in 4.8, as discussed in the link.

Relevant files: mining_manager.hpp
db.cpp

note This is a workaround for the CHECKMULTISIG bug.

This workaround seems to have been fixed in Bitcoin, so it might be able to be ported in some way to Vcash, although I could be wrong. Bitcoin PR here.

Relevant file: script.cpp
