ae.r now generated using def2write_r like cse?.r
fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.

These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. check-in: cc69033e71 user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk

10:54:13
Created branch optimise-algebraic-equations check-in: 22a486b2d4 user: gawthrop@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk

Trying to get rid of this! check-in: d73843e4d8 user: geraint@users.sourceforge.net tags: origin/master, trunk
14:52:15
Parameters in sfun reps are now declared using sympar.h at the top of the
sfun*.c file instead of in individual functions. This causes the optimisation
variables (mtt_tmp*) to be declared correctly without causing conflicts in the
scope of parameter declarations.
check-in: dc3ec712bc user: geraint@users.sourceforge.net tags: origin/master, trunk
14:48:34
Inclusion of sympar.h moved to top of file for consistency with other templates.

states and outputs prepended with an underscore to prevent conflicts when
inputs and outputs have the same names. check-in: 373df68651 user: geraint@users.sourceforge.net tags: origin/master, trunk

10:36:21
Fix for bug [553524] #define PI causes parse error.
Only substitutes for PI if it is not a number. This prevents Reduce from
trying to substitute for 3.14... when "on rounded" has been set.
