Big rename fest of MingW shared libraries
So far, MingW shared libraries were named like this
libeay32.dll + libeay32.dll.a
ssleay32.dll + ssleay32.dll.a
That naming scheme is antiquated, a reminicense of SSLeay. We're
therefore changing the scheme to something that's more like the rest
of OpenSSL.
There are two factors to remember:
- Windows libraries have no recorded SOvers, which means that the
shared library version must be encoded in the name. According to
some, it's unwise to encode extra periods in a Windows file name,
so we convert version number periods to underscores.
- MingW has multilib ability. However, DLLs need to reside with the
binaries that use them, so to allow both 32-bit and 64-bit DLLs to
reside in the same place, we add '-x64' in the name of the 64-bit
ones.
The resulting name scheme (for SOver 1.1) is this:
on x86:
libcrypto-1_1.dll + libcrypto.dll.a
libssl-1_1.dll + libssl.dll.a
on x86_64:
libcrypto-1_1-x64.dll + libcrypto.dll.a
libssl-1_1-x64.dll + libssl.dll.a
An observation is that the import lib is the same for both
architectures. Not to worry, though, as they will be installed in
PREFIX/lib/ for x86 and PREFIX/lib64/ for x86_64.
As a side effect, MingW got its own targets in Makefile.shared.
link_dso.mingw-shared and link_app.mingw-shared are aliases for the
corresponding cygwin-shared targets. link_shlib.mingw-shared is,
however, a target separated from the cygwin one.
