initdb

I now have a C implementation of initdb, which successfully runs with
"make check" on my several linux machines, and compiles on Windows/MinGW
too (can't run make check on Windows because we haven't got a native
postgres yet - I'm going to create a small dummy Windows postgres that
will let me check if this program works there).

There's a little work still to go (see below), but I'd appreciate some
eyeballs on it to see if I have made any major booboos, or could have
done things better. What's the best way to proceed? (All told it's about
2500 lines of C.)

cheers

From the heading comment:

/ *
* initdb
*
* This is a C implementation of the previous shell script for setting up a
* PostgreSQL cluster location, and should be highly compatible with it.
*
* TODO:
* - signal handling
* - more error checking, partiularly on the file i/o
* - check if we need workaround for timing error on win32 rmdir()?
* - clean up find_postgres code and return values
* - free up used memory? (probably not worth it - if we can't load this
* much data into memory how will we ever run postgres anyway?)
