# 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.
# start off configure.log
