Easy linker problem

I want to use function 'sleep' in a program.
When I compile my test prog with < gcc sleepTest.c -o sleepTest
-mno-cygwin >
I get:
$ gcc sleepTest.c -o sleepTest -mno-cygwin
/cygdrive/c/DOCUME~1/wallissd/LOCALS~1/Temp/ccW7l2vq.o:sleepTest.c:(.tex
t+0x5e):
undefined reference to `_sleep'
collect2: ld returned 1 exit status
Do I need a -lxxxxxx.a in the compile statement for the linker?
If so:
- how do I know which lib to use an a given situation, is there a
reference out there somewhere??
- have I buggered up my lib paths, shouldn't this stuff be found
automatically?
