This discussion reminds me of another long, long ago in a galaxy far, far away. (When I worked on "Mainframes" with 32 K or less "core" memory.) Discussing the then lopsided world with my non-IBM salesman, in a local watering hole, after a particularly trying day of dealing with "management."

[sqlite] Compiling Problem With SQLite 3.5.4

2007-12-15 Thread Robert L Cochran
