Hello *,

I've compiled cln-1.3.7 and ginac-1.8.8 by gcc-15.1.0 on Gentoo linux (I'm 
the maintainer of the ginal package in this distro). Everything's fine. 
But when I run ginac tests, I get

	Hello, Andrey!

	It seems the new version of GCC introduces the class complex, which
  was not there before. Now the compiler is confused which one to use:
  the previously existing cln::complex or std::complex. The attached
  simple patch shall resolve that.

  Best wishes,
  Vladimir

Yes, this is what I thought. Thank you very much for the quick fix. 
Committed to Gentoo.

I've disabled the GitWeb interface for the time being, because it was the 
target of a DDoS attack. It will be restored at a later date.
