port gv (leopard): compile-time bug in setenv.c

[Larry Snyder]

Hi.  I'm getting a compiler error in when I try to install 'gv':


   Command output: making all in ./source...
   /usr/bin/cc -Os -Wall -Wpointer-arith -no-cpp-precomp  -I/usr/X11/include
 	-D__i386__ -D__DARWIN__  -DNO_ALLOCA -DCSRG_BASED  -DNON_BLOCKING_IO
 	-DUSE_SIGNAL_HANDLER  -DUSER_DEFAULTS=\"~/.gv\"
 	-DGV_LIBDIR=\"/opt/local/lib/gv/\" -DGV_CODE
 	-I/opt/local/include -DUSE_FALLBACK_STYLES  -c -o setenv.o setenv.c

   <a number of warnings, e.g., implicit declaration of strlen and memcpy>

   setenv.c: At top level:
   setenv.c:105: error: conflicting types for 'unsetenv'
   /usr/include/stdlib.h:247: error: previous declaration of 'unsetenv'
 	was here

Here's what stdlib.h looks like:

  stdlib.h, lines 246-248
    #if __DARWIN_UNIX03
    int      unsetenv(const char *) __DARWIN_ALIAS(unsetenv);
    #else /* !__DARWIN_UNIX03 */


Here's the full history of what I did:
    upgrade to leopard
    installed X11 & developer tools from the leopard disk
    port gv                  <failed>
    port uninstall Xaw3d     <ok>
    port install   Xaw3d     <successful>
    port gv                  <failed, but got further than the first time!>

    port upgrade ghostscript <successful>

    ls -lt /usr/include/stdlib.h
 	<returns a timestamp indicating that it is a leopard version>

Can anyone tell me what the issue is?  Thanks!!
