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: ea9834becc user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk

10:54:13
Created branch optimise-algebraic-equations check-in: 28ad1630ec user: gawthrop@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk
10:54:12

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: bdfbe12d56 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: 0463689b2b 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.
check-in: adc4f01f84 user: geraint@users.sourceforge.net tags: origin/master, trunk
