COMP: TIOCGWINSZ and struct winsize also doesn't exist on Cray Catamount

Alex

COMP: make SystemTools.cxx build on Cray Xt3

Alex

ENH: add support for the Portland Compiler to CMake, can build cmake and the tests pass (except the wrapping tests, which fail to link to the g++-compiled Qt)

Alex

BUG: if there is no match, don't construct the stl string from a NULL
pointer

Alex

BUG: fix segfault if FindFiles() is called without actual match pattern
(e.g. FILE(GLOB /usr/include) instead of FILE(GLOB /usr/include/* )
#4620

COMP: Second try getting rid of Microsoft deprecation warnings. This time tested from KWStyle with vs8 to make sure the warnings are really gone. Remove the deprecation defs from CMakeLists and guard the defs in the header so we do not redefine them if they are already defined.

COMP: Suppress Microsoft deprecation warnings when building kwsys .c and .cxx files. This way, other projects that include kwsys will not see the warnings in kwsys .c and .cxx files, but they can still see the warnings in their own source files if they want to...

STYLE: fix typo

Alex

COMP: also build the static dummy loader on Cray Catamount

Alex

COMP: add a dynamic loader for systems which don't support dynamic loading, so this is handled in kwsys and not every project using this has to care for it

Alex

PERF: micro optimization: the (*pos1) && (*pos1=='/') were redundant, and
hasDoubleSlash is false in most cases, so in most cases 3 comparisons were
done, now only one

Alex

ENH: Added more special unix shell characters that require quoting.  Added escaping of % as %% for shells inside mingw32-make.

BUG: Do not send both SIGSTOP and SIGKILL when killing a process.  The SIGSTOP seems to be able to block the SIGKILL occasionally.  Also the SIGKILL is sufficient since the process table entry will still exist until it is reaped with waitpid.

COMP: Added istringstream::clear() method to disambiguate the call from using string::clear or istrstream::clear.

ENH: Added KWSYSPE_DEBUG macro to print debugging trace information.  Added TODO comment explaining why process execution can still hang when a grandchild keeps the output pipes open.

COMP: Fix warning about binding reference-to-non-const to an rvalue on VS6.  It does not seem to be doing the proper auto_ptr_ref conversions.  Instead use the const_cast work-around on this platform.
