When I define some macros in the compiler-options (-DXYZ) it seems as only c++ is affected by them and not gcc. If I add them by hand everything is fine, if not errors occur. Is this a fault by my - or can they somewhere else be set? tia, Ralf ------=_NextPart_000_01B2_01C0A2F4.C8C186E0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable
