Im getting the following error compiling a lot of our classes. I commented 15
places in the code to get around this error to try and get everything to
compile but now I get the following error compiling a project with 100 classes
but it doesnt say what class or line thats giving a problem so Im at a loss.
This seems to have been introduced over the last few days since the daily build
from about a week ago didnt seem to have the problem. I cant really give a
sample of the problem given its not telling me where the problem is originating
from.
