# Script to build Macintosh Universal Binary library of c-ares-1.5.3 for
# use in building BOINC.
#
# by Charlie Fenton 7/21/06
# Updated 9/30/08
#
## In Terminal, CD to the c-ares-1.5.3 directory.
##     cd [path]/c-ares-1.5.3/
## then run this script:
##     source [path]/buildc-ares.sh [ -clean ] [ -gcc33 ]
##
## the -clean argument will force a full rebuild.
##
## the -gcc33 argument will cause the PowerPC build to use gcc-3.3
## otherwise both architectures will be built using gcc_4.0
##
## Use -gcc33 if you need to link with a project application using BOINC 
## libraries built with gcc-3.3 for backward compatibility to OS 10.3.0
##
## Build with gcc-4.0 to link with the BOINC client
