The libc.a and libm.a in /lib are actually links to libcygwin.a -
the export library for cygwin1.dll. So what you need is a 
new libcygwin.a in your /lib dir and new cygwin1.dll.

How did you build the newlib package ? As part of cygwin build
process ? If this is the case then both libcygwin.a and cygwin1.dll
should been generated in winsup/cygwin/ - the cygwin1.dll is 
however named new-cygwin1.dll. So at this point you have to copy 
libcygwin.a to /lib and restore the libc.a and libm.a links and
also you have to copy new-cygwin1.dll in /bin/cygwin1.dll. Just
note that to overwrite the dll you have to exit all cygwin apps
including any services you might be runnig.
