This fixes the traversal of parent nodes using xmlTextReaderNext()
when the reader is based on a preparsed document (created using
xmlReaderWalker(doc)).
Without this fix the parser will abort even though there are parent
nodes it should traverse to, if it is not currently on an element or
attribute node. This is incorrect, since it can be for example on a
text node when it needs to enter backtracking.
Cygwin does not define _WIN32, but still requires dllexport/dllimport
tags for when applications use the --disable-auto-import linker flag,
probably set by the gl_WOE32_DLL autoconf macro in woe32-dll.m4 file.
Check whether aclocal.m4 contains the pkg.m4 macro package after running
autoreconf and print a more helpful error message.
Thanks to 林博仁 (Buo-ren Lin) for the initial patch.
Closes: #21
Currently the autogen script will always tell user to run make even
when the configure script failed, this patch changes the behavior to
only show this message when the configure script terminates without
error.

It seams this line was accidentally copied over from xmlCharEncOutFunc.
In xmlCharEncOutput output is a pointer so incrementing it by ret can
point it where it wasn't supposed to be pointing. Luckily the current
implementation doesn't dereference the pointer after advancing it.

If a nodeset to be filtered is empty, it can be returned without popping
it from the stack.
Make sure to restore the context node in all error paths and never set
it to NULL.
Save and restore the context node in RANGETO operations.
On some pre-C99 compilers, the NAN and INFINITY macros don't expand to
constant expressions.
Some MSVC versions complain about floating point division by zero in
constants.
Thanks to Fabrice Manfroi for the report.

This was used in xmlsec to detect issues with accessing external entities
and prevent them, but was unreliable, based on a patch from Aleksey Sanin
* parser.c: make sure input_id is incremented when creating sub-entities
for parsing or when parsing out of context
If libz or liblzma are detected with pkg-config, AC_CHECK_HEADERS must
not be run because the correct CPPFLAGS aren't set. It is actually not
required have separate checks for LIBXML_ZLIB_ENABLED and HAVE_ZLIB_H.
Only check for LIBXML_ZLIB_ENABLED and remove HAVE_ZLIB_H macro.
Fixes bug 764657, bug 787041.
CFLAGS shouldn't be touched by configure.ac. The variable is supplied by
the user and must come after other flags, so flags like warning options
can be overridden.
Rename CFLAGS to EXTRA_CFLAGS and add the value to AM_CFLAGS. This also
makes it possible to override flags for each Automake program or library.
Use C99 macros NAN, INFINITY, isnan, isinf. If they're not available:
- Assume that (0.0 / 0.0) generates a NaN and !(x == x) tests for NaN.
- Use C89's HUGE_VAL for INFINITY.
Remove manual handling of NaN, infinity and negative zero in functions
xmlXPathValueFlipSign and xmlXPathDivValues.
Remove xmlXPathGetSign. All the tests for negative zero can be replaced
with a test for negative or positive zero.
Simplify xmlXPathRoundFunction.
Remove Trio dependency.
This should work on IEEE 754 compliant implementations even if the C99
macros aren't available, but will likely break some ancient platforms.
If problems arise, my plan is to port the relevant trionan.c solution
to xpath.c. Note that non-compliant implementations are impossible
to fully support, anyway, since XPath requires IEEE 754.
