Re: Checking for GCC 4

[Harlan Stenn]

Yes, it is better to check for specific features/problems than to check
for a version number.

Sometimes it's Really Hard to check for features/problems.  Really
Really Hard.

Sometimes it is way more efficient to test for a version number than a
specific feature/problem.

I don't have any problem with that.

If the version test is discovered to be insufficient, to resolve that
insufficiency the test must be improved.

There are times I still do OS-version checks to >make assumptions<
about, for example, file system layout or startup script methods.

Is this inelegant?  Yes.  Have I received any bug reports about it?  No.

Software isn't finished until the last user is dead.

Evolution happens.

Some "issues" are more significant than others.
