#550 v34 fail to build as sharedlib

[marco atzeri]

Cygwin 64 bit.
The removal of main.c on recipe for libngspice.la, has left undefined variable around

My guess: please do not use configure flag

--with-readline=yes

nor

--with-editline=yes

It is not required for compiling the shared library. In ngspice-35 there also will be another safe-guard against the conflict shown above.

thanks, removing the flag works.
