Since round-tripping should not be a problem any more don't mention it.

This change fixes an important ordering issue - if element node has a PCDATA
child *after* other elements, it's impossible to tell which order the children
were in.

Since the goal of PCDATA embedding is to save memory when it's the only child,
only apply the optimization to the first child. This seems to fix all
roundtripping issues so the only caveat is that the DOM structure is different.

This is a bit awkward since preserving correct indentation structure requires
a bit of extra work, and the closing tag has to be written by _start function
to correctly process the rest of the tree.

When this flag is true, PCDATA value is saved to the parent element instead of
allocating a new node.

This prevents some documents from round-tripping since it loses information,
but can provide a significant memory reduction and parsing speedup for some
documents.

Also refactor to use the same case and run after common options.

scripts: Allow linking static CRT libraries on Windows

Use the solution from CMake FAQ to specify correct command-line arguments.

(!"string") triggers the warning however (false && "string") does not.

Fixes #75.

Apparently some MinGW distributions have a compiler that's recent enough to
support C++11 but limits.h header that incorrectly omits LLONG limits in
strict ANSI mode, since it guards the definitions with:

	#if !defined(__STRICT_ANSI__) && defined(__GNUC__)

We can just define these symbols ourselves in this specific case.

Fixes #66.

The tests now compile fine but crash on the first floating-point exception
despite our attempts to disable them in main()...

It does not have stdint.h and has some C++ parsing issues.

Fixes #61.

For some reason reference to a fixed-size array works in two other places
but not in this one...

These show up when building with Wcast-align for ARM.

Travis CI strikes once more.

It now also moves parse result.

Only happens on GCC 3.4 for some reason.

Fix "this decimal constant is unsigned only in ISO C90".
