Subject: Issue 182.
X-Git-Tag: v3.0.0a~59
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=049631350f291eb52e23a86d16bebbcbe377aa38;p=thirdparty%2Flibarchive.git

Issue 182.
Decide whether ZLIB_WINAPI is needed at configuration time, because there are two types of zlib
on Windows platform: one is built on Visual Studio, which requires ZLIB_WINAPI for use; other is
build on msys, which does not require ZLIB_WINAPI, GnuWin32 project provide such zlib.
