Installation problem - Mailing list pgsql-cygwin

Hi all,

   I've installed cygwin and on top of it postgresql 7.3.4 . Now I want to intall postgis on top  of postgresql. I've tried 0.7.1,0.7.3,0.7.4,0.7.5 versions .All of them are giving me errors saying "gcc exited with status 1, ld exited with status 1.... etc." can anybody suggest me wat might be the reason and how i can overcome this and install successfully.

 

Thanks in advance,
