Really? It's quite strange, I did exactely the same yesterday!

In fact, I was just looking if there was a patch for the bug I get. But 
there is not, and the debian package does have the very same bug. I 
succed in isolating the bug:
<523> address@hidden /tmp -> gcc tmp.c -Wall
<524> address@hidden /tmp -> ./a.out
Hello World
The end...
<525> address@hidden /tmp -> tcc tmp.c -Wall
/usr/lib/libc_nonshared.a: '__i686.get_pc_thunk.bx' defined twice
<526> address@hidden /tmp -> cat tmp.c
#include <stdio.h>
#include <stdlib.h>

void finish() {
 printf("The end...\n");
}
int main()
{
 atexit(finish);
 printf("Hello World\n");
 return 0;
}

Note that I get the very same error with fstat (IIRC).
I just made a new test: the very same binary tcc is working fine on an 
old system (sarge) and the problem occurs on a more recent one (etch). 
I'd like to give you the library version numbers:
Sarge system:
<504> address@hidden ~ -> dpkg -S libc_nonshared.a
libc6-dev: /usr/lib/libc_nonshared.a
<505> address@hidden ~ -> dpkg -l libc6-dev
[...]
libc6-dev            2.3.2.ds1-22sarge4   GNU C Library: Development 
Libraries and Header Files


Etch system:
<499> address@hidden ~ -> dpkg -S libc_nonshared.a
libc6-dev: /usr/lib/nptl/libc_nonshared.a
libc6-dev: /usr/lib/libc_nonshared.a
<500> address@hidden ~ -> dpkg -l libc6-dev
[...]
libc6-dev            2.3.6.ds1-11         GNU C Library: Development 
Libraries and Header Files


Any idea? Is there a problem with the more recent releases of libc6? 
Should tcc be fixed? Why is there the same file twice in the package? 
Could this be the problem origin?

Thanks for any help,

             "Requires Windows 95, NT 4.0, or better."
                   So... I installed it on Linux!
