[GiNaC-devel] ginac-1.8.8/cln-1.3.7/gcc-15.1.0 test failures

[Vladimir V. Kisil]

	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
