Problems with Constants (7)

	Change	Effect
1	The value of constant _IO_off64_t has been changed from _G_off64_t to __off64_t.	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.

	Change	Effect
1	The value of constant _IO_off_t has been changed from _G_off_t to __off_t.	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.

	Change	Effect
1	The value of constant _IO_pid_t has been changed from _G_pid_t to __pid_t.	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.

	Change	Effect
1	The value of constant _IO_size_t has been changed from _G_size_t to size_t.	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.

	Change	Effect
1	The value of constant _IO_ssize_t has been changed from _G_ssize_t to __ssize_t.	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.

	Change	Effect
1	The value of constant _IO_uid_t has been changed from _G_uid_t to __uid_t.	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.

	Change	Effect
1	The value of constant _IO_wint_t has been changed from _G_wint_t to wint_t.	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.
