# Script to build Macintosh Universal Binary library of c-ares-1.6.0 for
# use in building BOINC.
#
# Note: reverted to c-ares 1.6.0 from 1.7.0 because the newer c-ares has 
# problems resolving host names on OS 10.6 with default settings when used 
# with AT&T U-Verse 2Wire gateway routers and Airport.
#
# by Charlie Fenton 7/21/06
# Updated 12/3/09 for OS 10.6 Snow Leopard and XCode 3.2.1
# Updated 4/3/10
#
## In Terminal, CD to the c-ares-1.6.0 directory.
##     cd [path]/c-ares-1.6.0/
## then run this script:
##     source [path]/buildc-ares.sh [ -clean ]
##
## the -clean argument will force a full rebuild.
