First of all, learn to include the correct headers, and to write valid
C-code. Here's what you meant to type.
#include sys/stat.h
#include sys/types.h
#include fcntl.h
#include unistd.h
#include stdio.h
int main() {
if(mkdir(test, 0777) 0)
perror(mkdir1);
if(mkdir(test, 0777) 0)
perror(mkdir2);
return 0;
}
2nd of all, I get:
mkdir2: File exists
3rd of all:

Hello,
Today I stumbled on a really strange bug in Cygwin and Samba: errno 2 is
returned when attempting to create a file or directory that already
exists.
#include stdlib.h
#include unistd.h
void main() {
if(mkdir(test, 0777) 0)
perror(mkdir1);
if(mkdir(test, 0777) 0)
perror(mkdir2);
}
Gives a mkdir2: No such file or directory. huh?
This happens on more occasions; execute this on a mounted samba filesystem
under windows, like /cygdrive/p/...
import shelve
shelve.open(test, flag='c')
shelve.open(test, flag='c')
Traceback (most recent call last):

It gives an 'No such file or directory' the second time, while the shelve
is succesfully created. It seems to produce this error when a file already
exists.
This essentially makes shelve useless under cygwin.
