The project is already with #ifdef, but it's kind of dirt, and pragma avoids messing up with repeated CLASS_NAME on ifdefs.
I think that the problem with prama once in old compilers is when you have 2 links to the same file, and that I can control.
So if I could suppress this specific warning...
But if is there more implications (like the pragma is completely ignored) than the 'two links bug' I'll put it aside.

Obs.: The 'crap message' will be appended again, please, ignore it. I can't configure other mails on my network, but I'll try to handle it. Just for now, just for this thread, please, ignore the 'crap part'.

Reference:
If the compiler makes a mistake, for example by failing to recognize that two symbolic links with different names point to the same file, then the compilation will fail.

	The proper fix is to replace the non-standard "#pragma once" clauses by

	grep -v will probably not do what you expect - it is likely to trigeer
	other errors due to muliple inclusions.
