- backported code that handles %f/%g arguments in 
my_vsnprintf.c from 6.0 
- backported %f/%g tests in unittest/mysys/my_vsnprintf-t.c 
from 6.0 
- replaced snprintf("%g") in sql/set_var.cc with my_gcvt() 
- removed unnecessary "--replace-result"s for Windows in 
mysql-test/suite/sys_vars/t/long_query_time_basic.test 
- some test results adjustments

Unlike other platforms --mfpmath=sse is the default 
gcc mode on Mac OS X Intel. So it is unnecessary
to switch FPU to double precision mode (in fact,
it even breaks some math library functions).

                      to string conversions and vice versa" 
Initial import of the dtoa.c code and custom wrappers around it 
to allow its usage from the server code. 
 
Conversion of FLOAT/DOUBLE values to DECIMAL ones or strings 
and vice versa has been significantly reworked. As the new 
algoritms are more precise than the older ones, results of such 
conversions may not always match those obtained from older 
server versions. This in turn may break compatibility for some 
applications. 
 
This patch also fixes the following bugs: 
- bug #12860 "Difference in zero padding of exponent between 
Unix and Windows" 
- bug #21497 "DOUBLE truncated to unusable value" 
- bug #26788 "mysqld (debug) aborts when inserting specific 
numbers into char fields" 
- bug #24541 "Data truncated..." on decimal type columns 
without any good reason"
