Problems with Constants, Low Severity (2)

	Change	Effect
1	The value of constant TCL_LL_MODIFIER has been changed from "L" to "ll".	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
