[Discuss-gnuradio] Problems building Gnuradio on Cygwin

[Achilleas Anastasopoulos]

Hi all,

I am following the instructions to install gnuradio-core-2.3
on cygwin (windows xp) and I get the following problem
with make (using gcc/g++ 3.4.1)

Any suggestions what might be wrong here?

Thanks
Achilleas
