Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler) Added a lot of 'version_xxx' strings to 'show variables' Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris) Fixed problem with printing sub selects to debug log

NOTES
|
|
Ordinary ownership and accesstimes are copied from 'from-file'
|
|
If MyFlags & MY_HOLD_ORIGINAL_MODES is set and to-file exists then
|
|
the modes of to-file isn't changed
|
|
If MyFlags & MY_DONT_OVERWRITE_FILE is set, we will give an error
|
|
if the file existed.
|
|

WARNING
|
|
Don't set MY_FNABP or MY_NABP bits on when calling this function !
