can sb know why (newest download cygwin) after compiling in "as" such a code:
.global _start _start: movl $1,%eax movl $0,%ebx int $0x80 when i link with "ld" it shows warning about mainCRTstartup . .and when i try to run .. it crashes before code executed! and why such a simple program needs mainCRTstartup?
