Subject: Fix zlib configuration options.
X-Git-Tag: OpenSSL_1_1_0-pre5~53
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=62890f47288687e4f0b7b2c1ce2da7c93ef21063;p=openssl

Fix zlib configuration options.

The macros ZLIB and ZLIB_SHARED weren't appropriately defined,
deviating wrongly from how they worked in earlier OpenSSL versions.
So, restore it so that ZLIB is defined if configured "enable-zlib" and
so that ZLIB and ZLIB_SHARED are defined if configured
"enable-zlib-dynamic".

Additionally, correct the interpretation of the --with-zlib-lib value
on Windows and VMS, where it's used to indicate the actual zlib
zlib library file / logical name, as that can differ depending on zlib
version and packaging on those platforms.

Finally for Windows and VMS, we also define the macro LIBZ with that
file name / logical name when configured "zlib-dynamic", so the
compression unit can pick it up and use it.
