Subject:	Pyclewn doesn't run because Cygwin gdb's version string is non-standard

Hi,

I am trying to run Pyclewn (gdb front end for Vim) under Cygwin. Installation
went fine, but when starting Pyclewn, it starts gdb and attempts to determine
the version number:

Exception in pyclewn:

<class 'clewn.__init__.ClewnError'>
"cannot find the gdb version"
source line: "raise ClewnError('cannot find the gdb version')"
at /usr/lib/python3.2/site-packages/clewn/gdb.py:357

pyclewn aborting...



The cause appears to be that the version number reported by Cygwin gdb is
non-standard, Pyclewn doesn't like the "(cygwin-special)" after the verison
number:

    GNU gdb (GDB) 7.6.50.20130728-cvs (cygwin-special)

The relevant bit of Pyclewn is

def parse_gdb_version(header):
     r"""Parse the gdb version from the gdb header.

     From GNU coding standards: the version starts after the last space of
the
     first line.

     >>> DOCTEST_GDB_VERSIONS = [
     ... r'~"GNU gdb (GDB) 7.5.1\n"',
     ... r'~"GNU gdb (Sourcery CodeBench Lite 2011.09-69)
7.2.50.20100908-cvs\n"',
     ... r'~"GNU gdb (GDB) SUSE (7.5.1-2.5.1)\n"',
     ... r'~"GNU gdb (GDB) Fedora (7.6-32.fc19)\n"',
     ... r'~"GNU gdb (GDB) 7.6.1.dummy\n"',
     ... ]

I checked the gdb source code, and it appears that the comment in Pyclewn
is correct w.r.t. the format. Here is the relevant bit of top.c:

/* Print the GDB banner.  */
void
print_gdb_version (struct ui_file *stream)
{
  /* From GNU coding standards, first line is meant to be easy for a
     program to parse, and is just canonical program name and version
     number, which starts after last space.  */
