Hi !


I guess I'm seeing a differnet problem then . It looks like
I need to tell gcc what the default libs are. from the info page
it loooks like libgcc.a is required to fix up a few things so
this also is now copied into the glibc-2.0.7 directory and now used

gcc -nostdlib -nodefaultlibs -L../../glibc-2.0.7/ -lc -lgcc -s -o hello hello.c

which works fine if I DON't use 

   return 0;

at the end of the program but rather put in

    exit(0);

if I use return it will run and then segfault at me . So I guess its not enough
to have -lc (for libc) and -lgcc (for libgcc) in the compiler flags . 

any hint ?

thx !
