-# configure script for zlib. This script is needed only if

-# you wish to build a shared library and your system supports them,

-# of if you need special compiler, flags or install directory.

-# Otherwise, you can just use directly "make test; make install"

-#

-# To create a shared library, use "configure --shared"; by default a static

-# library is created. If the primitive shared library support provided here

-# does not work, use ftp://prep.ai.mit.edu/pub/gnu/libtool-*.tar.gz

-#

-# 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)

-# LDSHARED is the command to be used to create a shared library

-

-# 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.
