system inc and dynamic linker change

[KRAJCSOVITS Gyorgy]

Hi, thanks for the reply,

   yes -Wl,--dynamic-linker works, but when I'm compiling big programs it 
is sometimes impossible (ok, very hard) to change the linker for every 
link step. It would be better to have gcc (or ld) automatically do this.
   And I need gcc to search other directories for system header files as 
well.


bye, krajo
