Re: Force -O0 flags, inhibit the default -O2 flags

[Brian]

We have several files which are not able to be optimized, and when our mac
mini tries to build the project it chokes up when attempting to do so. It
seems incorrect to say that the package developer is the least qualified to
judge compiler flags, and it also seems to avoid the point. The package
developer should be able to override the autotools, and the user should be
able to override the developer. It is not a matter of qualification, it is a
matter of the chain of command. Right now the chain of command is user -->
autotools --> developer. In reality it should be user --> developer -->
autotools.

Thanks for the comments - a most distressing problem,
Brian
