allow building GDB with Python support on MinGW
This makes several adjustements to the configure python-config.py
scripts to deal with the differences between a Unix install of Python
and a Windows install of Python (as downloaded from the Python website).
Differences:
- The Python executable is directly in the python prefix directory
as opposed to inside the bin/ subdirectory.
- The name of the python library is does not have a dot in the version
number: On Unix, we have libpython2.7, while on Windows, it's
libpython27. So the regexp extracting the python version from
the Python lib filename had to be adjusted slightly.
Also, the tests checking the name of the libpython had to be
adjusted to allow for that.
- There are no link options following the -lpython<version> switch
on Windows, but the regexp extracting the python version was
using it as a delimiter. It had to be removed.
- python-config.py does not work on Windows, mostly because
some sysconfig variables are missing. They are not necessary
so the script was adapted to skip them if not defined.
- The paths returned by python-config.py follow the Windows filename
convention in terms of the directory separator, and this is causing
trouble when the build environment is cygwin (while the compiler
and Python are MinGW). We could have fixed that in the configure
script, but it felt simpler to do so in python-config.py
gdb/ChangeLog:
* configure.ac: Add handling of Python distribution on Windows.
* python-config.py: If the LIBS, SYSLIBS, LIBPL and/or LINKFORSHARED
sysconfig variables are not defined, then do not use them.
On Windows, if LIBPL is not defined, then use prefix + '/libs'
instead. On Windows, return all paths using forward-slashes
rather than backslashes.

do not use python<version> subdir when including Python .h file
This is preparation work for being able to build GDB with Python
support on MinGW.
So far, the "python<version>" subdirectory needs to be specified
when including a Python header file. In order to do that, we have
some special configury that tweaks the include path returned by
python-config.py such that the use of the subdirectory in the include
is necessary. This was done in order to protect ourselves from
possible filename conflicts, since some of the filenames chosen by
Python were a little generic.
The problem is that this cannot work with a standard Python install
on MinGW systems. On such systems, the .h files are located in
<python_prefix>/include. So, in preparation for allowing us to build
GDB on MinGW with Python support enabled, this patch changes the
requirement to provide the "python<version>" subdirectory in the
include directive.
The positive consequence is that we no longer need to have a set
of #include directives for each version of Python, since the include
directive is now the same for all versions of Python. However, the
downside is that we are losing the level of protection we were trying
to achieve by forcing the subdirectory in the include directive.
In order to reduce a bit the consequences of a possible conflict,
this patch also changes the location where the -I/path/to/python
switch goes, to be last in the list (suggested by Doug Evans).
One last change is the fact that we are now including Python.h
and all other Python include headers using angle brackets rather
than double-quotes. This fixes a problem on case-insensitive
systems where #include "Python.h" causes our gdb/python/python.h
header to be included instead of Python's <Python.h> header.
gdb/ChangeLog:
* configure.ac: Remove fallback behavior for building
against Python. Remove tweaking of Python include path.
Add PYTHON_CPPFLAGS and PYTHON_LIBS substitution.
(AC_TRY_LIBPYTHON): Adjust program used in linking test.
If link is successful, set PYTHON_CPPFLAGS and PYTHON_LIBS.
Always restore CPPFLAGS and LIBS after linking test.
* configure: Regenerated.

(INSTALLED_LIBS, CLIBS): Add @PYTHON_LIBS@.
