OpenBSD's 'pmake' chokes on these.

The '$<' variable is not guarantee to work in ordinary make rules by
non GNU make implementations. In addition if it is supported it will
be replaced by the actual source pathname (in VPATH mode), which is not
the relative name we need on installation.

Detect as many warnings as possible during configure and enable them
if the user did not supply any, so that any such problem can be spotted
and fixed.

Exclude test suite files from the coverage which incorrectly increase
the coverage percent. Build with no-optimizations and debugging symbols.

On Windows we cannot use proper aliases, and using the /EXPORT linker
flag is too cumbersome, as it does not work when static linking, and
when dynamic linking it does not make the aliases visible within the
DLL itself.

Just use normal function wrapper in those cases, which are way more
maintainable.

Adding local-link.h as private header file requires $(srcdir) on
AM_CPPFLAGS to be found by generated sources when builddir != srcdir.

Do not use libmd.sym from $(srcdir), as it is a generated file.

This is not a generated file, so it needs to be listed in the library
SOURCES variable.

There is no good reason to have these as weak symbols at all. And it
makes building on Windows (Cygwin, MinGW) harder as it does not
support weak symbols.

This provides several macros for versioned symbols and linking magic.

These are not currently used, as they are not part of the versioned
symbols export map.

Some target platforms do not have <unistd.h>, notably Windows when
using vanilla MSVC toolchain. Note: The AC_CHECK_HEADERS([unistd.h])
is redundant with LT_INIT, but there is no guarantee for that.

 - Use AC_CHECK_HEADERS instead of AC_CHECK_HEADER.

This will be guarded by a LIBMD_MD5_ALADDIN macro check, to avoid
polluting the namespace by unsuspecting code. The macro can always
be defined unconditionally, and the guard could even potentially
be removed in the future if required.

Generate the base test function with a maro, because all of them follow
the same pattern. And extend it by covering more of the API.

These have swapped names in their macro values.

The previous sed expression only worked with GNU sed, as the '\+'
literal is an extension to basic regex. Use portable syntax instead that
also works with other implementations of sed(1), for example on macOS.

This is an obsolescent practice, just stop conditionally using this
macro.

There are platforms without <sys/param.h>, so we better avoid the
header altogether, and add the required MIN macro outselves.

Extend it instead via EXTRA_*_DEPENDENCIES, to make sure that we
preserve the builtin library dependencies generated from LIBADD.
