Summary:                    fseek() does not propagate back errno
Description: 
Compile and run the attached C program linked against uClibc.

Both lseek() and fseek() return -1 as evidenced by the output coming from
perror(), but fseek() has errno = 0, while lseek() has errno = ESPIPE.

Using the latest (svn) uClibc, your program produces the following output
in my test environment:

lseek: Illegal seek
fseek: Illegal seek

Bug already fixed? Do you have LFS enabled (I do)? I will try checking
with 0.9.28.1

We found the problem with 0.9.28.3.  Is this fixed with 0.9.29?

And yes, we have LFS enabled.

Close out the bug, please.  We found the error in the system call, not
uClibc.
