open_() returns always -1

Hi,

I had to use open_() in a PB code.
It was never working. I always got -1 as answer.

Then I imported it by myself and it was working.

Failing:

Code:

ImportC ""
   errno_location() As "__errno_location"
EndImport

#O_RDWR  = $00000002

fd = open_("/tmp/test", #O_RDWR, 0)
If fd > 0
  Debug "open"
  close_(fd)
Else
  Debug "open failed"
  Debug PeekL(errno_location())
EndIf

Working:

Code:

ImportC "/usr/lib/x86_64-linux-gnu/libgc.so.1"
  open.i(path.p-UTF8, flags.i, mode.i)
EndImport

ImportC ""
   errno_location() As "__errno_location"
EndImport


#O_RDWR  = $00000002

fd = open("/tmp/test", #O_RDWR, 0)
If fd > 0
  Debug "open"
  close_(fd)
Else
  Debug "open failed"
  Debug PeekL(errno_location())
EndIf

You have to touch /tmp/test before.
