- too big number:
strat.h->StrategyEvaluationData->StrategyExpression expression[12]
^^
- so 12 is real max # of strategies, or StrategyEvaluationIsValid
crashes backend (called if CASSER defined).
Subject: [PORTS] minor fix for DGUX port
src/include/port/dgux.h needs the following three lines appended:
#ifndef BYTE_ORDER
#define BYTE_ORDER BIG_ENDIAN
#endif
I believe this to be correct for DG/UX on M88k processors. I don't have one of
the new Intel-based boxes to check on.
Include some additional path functions which were coded but omitted here.
Add translation and rotation/scaling operators for some geometric types.
Fix bugs in some geometry comparison operator declarations.
Subject: [PATCHES] port patch: ultrix4
ultrix4 doesn't compile without this. this also fixes a problem
with dynamic loading (ultrix relocatable objects must be loaded
with -G 0).
Add mixed-case #define synonyms to avoid changing more source code.
Add comparison operators for boolean.
Add aggregate min() and max() for datetime and timespan.
Here are patches which should help fix timezone problems in the
datetime and abstime code. Also, I repatched varlena.c to add in
some comments and a little error checking on top of Vadim's earlier
repairs. There are slight mods to the circle data type to have the
distance operator between circles measure the distance between
closest points rather than between centers.
