zlib/configure
Mark Adler 2dadd2fab4 Use name in GCC_CLASSIC as C compiler for coverage testing, if set. 
Apple removed support for gcov in the default gcc compiler chain,
when they moved to llvm.  This can be circumvented in XCode 4.2 by
using the gcc chain with gcc-4.2.  This patch allows setting
GCC_CLASSIC to the name of a real gcc executable (e.g. "gcc-4.2")
to allow coverage testing.

# 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.
