Robert, I know that, i didn't expect whatever was compilied to actually work
as it should, I just wanted it to compile....

the client

Well as I said initially it was complainig about a missing sys/acct.h

Then when I used the BSD version of the file, the compilation proceeded and
I got the following error:

os.c: In function `utmp_to_packets':
os.c:398: `S_IFCHR' undeclared (first use in this function)
os.c:398: (Each undeclared identifier is reported only once
os.c:398: for each function it appears in.)

This didn't seem to have anything to do with the wreckless use of acct.h, so
I continued my dodgy wreckless behaviour, found the instance of S_IFCHR  (it
only appeared once in the source, and killed it). Again this will probably
produce a finger that doesn't work...but hey ;-)

Then got:

tty.c: In function `get_last_access':
tty.c:96: `S_IFMT' undeclared (first use in this function)
tty.c:96: (Each undeclared identifier is reported only once
tty.c:96: for each function it appears in.)
tty.c:96: `S_IFLNK' undeclared (first use in this function)

more wrecklessness...and then

finger.c: In function `call_finger':
finger.c:234: warning: passing arg 1 of `gethostbyaddr' from incompatible

../lib/libfinger.a(os.o)(.text+0xa3):os.c: undefined reference to

ah well ;-)
I've never written any C before, so I doubted that I'd be able to figure out
what was going on, so i decided to leave it.....but since you asked so
nicely for the errors I pulled everything again and thus the above report.
Obviously getting the finger client to work on cygwin isn't as
straightforward as I'd hoped.
