by checking the codes, i could see temp_store_directory is used to overide
the platform-specific default temp directory in run time.
That is, if temp_store_directory is 0 (the default value of
temp_store_directory), then OS layer (os_win.x and os_unix.x) will provide
the OS default temp directory. (for example, */var/tmp, /usr/tmp for unix*).
if temp_store_directory is configured by pragma, then the
configured temp_store_directory will be used instead of OS default one.
the following code is from os_win.c :: sqlite3WinTempFileName()
if( sqlite3_temp_directory )
{
... ...
}else if( isNT() )
{
... ...
}

I can see your point, I guess, though I can't say that it seems like
a major issue to me.
Just out of curiosity, why aren't the defaults derived in os_win.x
and os_unix.c sufficient?
