Commit Message

Diego Novillo Sept. 4, 2012, 6:31 p.m. UTC 
This patch works around a parsing problem with g++ 4.3.  The parser is
failing to lookup calls to the template function reserve when called
from other member functions:

vec_t<T>::reserve<A> (...)

The parser thinks that the '<' in reserve<A> is a less-than operation.
This problem does not happen after 4.3.

This code is going to change significantly, so this won't be needed
soon.

Tested on x86_64 with g++ 4.3 and g++ 4.6.


Diego.
