Adds ARFLAGS variable for options, where AR is now just the command name. So now $(AR) $(ARFLAGS) is used to build the static library.

# configure script for zlib.

#
|
|
# Normally configure builds both a static and a shared library.
|
|
# If you want to build just a static library, use: ./configure --static
|
|
#
|
|
# To impose specific compiler or flags or install directory, use for example:
|
|
# prefix=$HOME CC=cc CFLAGS="-O4" ./configure
|
|
# or for csh/tcsh users:
|
|
# (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
|
|
|
|
# Incorrect settings of CC or CFLAGS may prevent creating a shared library.
|
|
# If you have problems, try without defining CC and CFLAGS before reporting
|
|
# an error.
