Yes.

Hmmm. As I stated before it acts like there would be a file named 'all'
which is up to date. Meanwhile I have also detected some strange behavior
of gunzip (tells me that the output file already exists...) which gave me a
hint where to search for a bug, and....... BINGO !
From the gzip sources I got that piece of source code that is testing files
and created a little test program (available upon request).

!! I found out that when running WinNT4.0 the stat() function is returning 0 !!
!! for non-existing files (no matter if file system is FAT or NTFS). !!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Here is a dump of the returned stat structure for a non-existing file:
st_dev = 3
st_ino = 0
st_dmode = 0
st_uid = 42
st_gid = 42
st_rdev = 0
st_size = 0
st_atime = 312768000
Due to the functionality of a make utility I strongly suspect that it is using
stat() or one of the related functions for checking files. This would explain
the misbehavior of make.
As I have neither knowledge of how the stat() function is implemented nor detailed
knowledge of WinNT, I would like to ask if someone out there could have a look at
the libc source to fix this. Maybe the other related functions are buggy too.
