hi list, I see that I have all of these file in /usr/lib/ : /usr/lib/crt1.o /usr/lib/Scrt1.o /usr/lib/Mcrt1.o /usr/lib/gcrt1.o but when I compile with "-v" I see that only crt1.o is used. so what are all the others ? are they part of glibc too ? what are the differences between them ? thanks !! metuki
