[Zlib-devel] ZLIB_VERSION calculation proposal

[Andrei Polushin]

Hello,

I would like to propose version calculation mechanism for zlib. The idea is
to split version macros into separate parts, and then calculate original
values. The direct objective is to simplify maintenance of Win32 build,
which require different form of version representation (separated by
commas). If the patch were accepted, we will be able to rewrite .rc files in
win32 directory in a way that they will not require version maintenance.

With best regards,
// Andrei Polushin
