You mean that
        HAVE_PROGRAM_INVOCATION_NAME
was not set, then this is good, then you should have
a lib/pin.c and lib/pin.o

# cd mailutils/lib
# gcc -DHAVE_CONFIG_H -E -I .. -I ../include pin.c

If things where ok you should see the definitions of
the variables.

They should not be defined since it appears that on cygwin
libc does not provide them.

It's the other way around, comment out the HAVE_PRORAM_INVOCATION_NAME
to let lib/pin.c define the variables.

If it is that all you need, then it should be sufficient.

Sorry, I do not have a cygwin system to test.
