[GRASS5] Help with zlib.h

[VENKATARAMANAN RAJAGOPALAN]

Hello,
I was trying to compile a simple program from
http://www.geog.le.ac.uk/jwo/teaching/c_prog/12interface/index.html
and the compiler prints that the following things were missing:
inflateInit_, inflate,inflateEnd, deflateInit_,deflate,deflateEnd.  I am
trying to compile it with the latest version(stable) of GRASS.

can someone help me rectify this???

thanks
