change this to:
LIBS = -lc

It is a known problem that adding -lcygwin and -lkernel32 will cause

-------------------- IMPORTANT UPGRADE NOTICE ------------------------
You should get the following to update your cygwinb19 package:

Sergey Okhapkin's coolview package which contains an updated 
cygwinb19.dll.  (Yes, even if you've already downloaded the b19.1 
update from the Cygnus Site).

Mumit Khan's compilation of EGCS for the cygwinb19.dll; especially if 
your using the C++ compiler.  The current version of the compiler that 
comes with the tools have lots of problems that have been fixed with 
the EGCS version.  This is a drop-in replacement for the GCC toolset.

URL's are listed above.
