prt1 first, and crtbegin ownmodule crtend I believe, I added the others to
the end, and that worked. (But I didn't link libc or any other lib)
So
crt1 crtbegin myobject crtend crti crtn.
P.s. Could you sent me a minimal C program linking to libc, and the
commandline to compile it with -nostdlib ?
I could throw all these experiences with non standard linking in a little tex doc.
( --nostdlib with and without libc, pure assembler instead of c (no gcc), some
small chapter about syscall conventions etc)
