+echo. The cflags and ldflags arguments support parameters that include the =

+echo. separator character you will need to enclose any parameter that includes
+echo. the = character in quotes.  For example, to include
+echo. -DSITELOAD_PURESIZE_EXTRA=100000 as one of the cflags you would run
+echo. configure.bat as follows:
+echo. configure.bat --cflags "-DSITELOAD_PURESIZE_EXTRA=100000"
+echo.
+echo. Note that this capability of processing parameters that include the =
+echo. character depends on command extensions.  This batch file attempts to
+echo. enable command extensions.  If command extensions cannot be enabled, a
