Always create only two SimGear libraries: SimGearCore and SimGearStatic, regardless of whether we're building static or shared. This requires an updated to FindSimGear.cmake module, for the static configuration.
the MSVC and MipsPro warning stuff).
As a result of this patch, simgear/sg_traits.h can be deleted. So can SGCMath.h,
but I'll do that separately.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another mechnica

As in subdirectory foo/bar, $(top_builddir)/foo/bar is defined to be the
current directory, this does not cause any regressions.
From Hans Ulrich Niedermann (hun@n-dimensional.de)
- new FSF address
- removed a few hundred trailing spaces
- fixed a few $Id$ lines
- copied two license headers from *.hxx files to their respective
*.cxx counterparts
- added two test aps to .cvsignore
- don't unlock an already unlocked mutex (Someone wanted to be on
the safe side with this, but the result is undefined and makes
pthread_mutex_destroy fail. Reference: manpage for
pthread_mutexattr_gettype/The Open Group[1]: "Attempting to
unlock a mutex of this type which is not locked results in
undefined behaviour.")
- re-enabled all subsystem destructors again (this has been disabled
because fgfs hung on exit, due to the mutex destroy failure)
- Removed some old cruft.
- Removed some support for older versions of automake which technically was
correct, but caused the newer automakes to squawk warnings during an
initial sanity check (which isn't done very intelligently.)
NOTE: this fix is technically not correct for older version of automake.
These older version use the variable "INCLUDES" internally and could have
them already set to an important value. That is why we were appending
our values to them. However, newer versions of automake don't set this
value themselves so it is an error to append to a non-existant variable.
We seem to "get away" with overwriting the value on older versions of
automake, but if you have problems, consider upgrading to at least
automake-1.5.
- automake-1.4 sets default values for INCLUDES which we can't
overwrite.
- automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES
open for the developer to use.
Thus for automake-1.4 we are forced to 'append' to INCLUDES and in
automake-1.5 we can just set the value to whatever we like.
Unfortunately, the behaviors of the two versions are mutually
incompatible.
The solution I am committing now works for both versions but
automake-1.5 generates a lot of spurious warning messages that are
annoying, but not fatal.
flightgear, especially when this occurs in a simgear .hxx file. This is
now expressly forbidden, and will cause problems anyways because we now
changed the name to <simgear_config.h> which isn't installed, so you can't
include it in an installed header file.
magnetic variation for a specific location and date without running an
update cycle (I use this for setting up VOR default offsets in some
FlightGear patches).
2. [CRITICAL] Fixed some null-pointer bugs in simgear/misc/props.cxx.
Classic space vs time seemed worth it in that we get a ~3 fold speedup
for ~5% space increase here. Also pow() is an expensive Fortran to C
translation in just about all the old government code I see :))
