works with 1.2+. when adding -w, or any special flags, be sure to add
them and not replace the original flag.
system/var.c: 64bit clarity.
system/discrete.c: 64bit clarity.
system/analyze*: g_reuse declared in wrong place. 64bit clarity
system/diffvars: missing prototype function, 64bit clarity.
compiler/numlist.*: changed from int to glint.
compiler/simlist.c: missing includes needed for 64bit clarity.

Changes to the way in which sovlers are registered, to facilitate
dynamically-loaded solvers. Also split much of the 'solver' stuff
from slv.c (in the system directory) out into new file solver/solver.c
and added matching solver/solver.h. Solver IDs are now fixed-- they
don't change, and are stored in a list instead of in an array.

Another one of these big refactorings. Split out 'system' directory from 'solver' directory. This will need more work
but it's a start at getting the non-solver-specific code out separately.

routine so that *any* requested output can be retrieved from the integrator (for the case

Added new 'destroyfn' parameter (as NULL) to all calls to 'CreateUserFunctionMethod'.

Some success with IDA: fixed up the indexing dilemma and was able to
integrate 'johnpye/thermalequilibrium.a4c' for a short time span (but
through to 3000 s as with LSODE). I would blame lack of jacobian routine
in the first instance.

Added 'more properties' button in Properties dialog for a variable, to allow
values of ode_id, ode_type etc to be queried (but not changed).

Converting dsg.a4c into a dynamic (IVP) model.
Removed some debug output from various places.
Renamed some functions in lsode.c (removed references to 'blsode' name)
Added comments in LSODE about what method is being used.
Improved LSODE error output a little bit (why bother tho eh)
Improved coupla error msgs in slv_stdcalls.c.

First tentative version in 'integration reporting':
Values of observed variables from the simulation are added to an Observer table after simulation completes.
This is not very efficiently coded at this stage but is a start.
Also some minor changes to text and comments in some base/generic files.

Monster commit!
Lots of recommenting and reorganising of external relations-related stuff.
Replaced a lot of ascmalloc and asccalloc calls with the new ASC_NEW* macros.
Fixed (?) the problem Art is having with icons in PyGTK.
Turned on -Wall in SConstruct and fixed up a stack of warnings.
Removed the redundant exit(2) from after Asc_Panic calls and added __attribute__((noreturn)).
Set doxygen to create callgraphs to level 2, updated doxyfile to version 1.4.7.
Fixed up building of extfntest.c.

- fixed a minor bug in the use of dimensions in samplelist
and a #define misuse in ospath.
- defined eolstyle unix on the trunk, as I have encountered
at least 4 too many mixed-eol-style-in-one-file files in trying to 
rebuild today. obviously committer discipline is insufficient.

Merged changes from DAE branch (revisions 702 to 819) back into trunk.
This adds the Integration API to the ASCEND solver (in base/generic).
Also provides pre-alpha support for 'IDA' from the SUNDIALS suite, a DAE solver.
Many other minor code clean-ups, including adoption of new 'ASC_NEW' and friends (to replace 'ascmalloc')
Added some very sketchy stuff providing 'DIFF(...)' syntax, although it is anticipated that this will be removed.
