If I build SQLite 77c692a6 (trunk) with CFLAGS="-DSQLITE_OMIT_FLOATING_POINT"
I get a bunch of errors. Here is a patch in 3 parts that would fix this issue:

* SQLite-77c692a6-double-fix-part-1.diff - fix sqlite.h.in to use a proper
  typedef to define a new sqlite_double typedef instead of using a macro
  to overwrite double

* SQLite-77c692a6-double-fix-part-2.diff - fix other headers to use
  the new sqlite_double typedef instead of double

HOWTO: Using FileMerge (opendiff) with Git on OSX

FileMerge (opendiff) can really come in handy when you need to visually compare merging conflicts. Other times it's just a nice visual way to review your days work.

The following method works by creating a simple bash script (git-diff-cmd.sh) that sets us up with the proper command line arguments for Git to pass off files to FileMerge.
