Ignore gcc-4.3 warnings

[Balazs Dezso]

The semicolon after directly the closing parse of a for loop emits warning.
Constant non reference return value emits warning.

Solution for ignoring warnings.

I suggest postponing this until all of the planned components of release 1.0 is in the repository.

One new type of data error is introduced in new gcc-4.3:
typedef SomeClass?<Param> SomeClass?;
emits error. It is used quite often in LEMON, but it can be solved with explicit reference to the namespace of SomeClass? template class.

Replying to deba:

One new type of data error is introduced in new gcc-4.3:
typedef SomeClass?<Param> SomeClass?;
emits error. It is used quite often in LEMON, but it can be solved with explicit reference to the namespace of SomeClass? template class.

In fact, it says something like this:

./lemon/bits/bezier.h:35: error: declaration of ‘typedef class lemon::dim2::Point<double> lemon::dim2::BezierBase::Point’
./lemon/dim2.h:53: error: changes meaning of ‘Point’ from ‘class lemon::dim2::Point<double>’

which is clearly stupid. Anyway, [716b220697a0] fixes this error and a couple of others.

I use gcc-4.3 as a default compiler from now on, so I close this ticket.
