[GRASS5] configuration/build failure on solaris 8, curses and get/putwc

[Wallace, Beverly T]

I had the same problem with curses.  I fixed it by ignoring warnings.  
Set the following before running configure:
   setenv CPPFLAGS -w
Also, make sure that GNU make and tar are found first:
   setenv PATH /usr/local/bin:$PATH
