For #pragma pack(packed), the z/OS 1.8 compiler issues an informational message saying that support may be dropped in a future z/OS compiler release, and that the statement should be replaced with #pragma pack(1). Increased the size of certain declared arrays in the ./rt/base/caormg.c, ./rt/base/cleo.c, and ./rt/base/crlr.c segments and in the ./include/i$ps.h header by one array element because code may reference or store beyond the end of the array. Changed the initialization of the tmpDispBuf array in the ./rt/base/cuscpf.cpp segment from = {}; to = "" to avoid a compiler warning message. Changed code in ./rt/base/ceatad.c to eliminate a compiler warning and also added detailed maintenance comments to explain how fields are laid out in the structures when dereferencing. Created the ./include/tpf/c_terminate.hpp header as a permanent workaround for an unresolved reference warning message caused by the z/OS 1.8 prelinker/linkage editor and by any future z/OS prelinker/linkage editors.

MIGRATION CONSIDERATIONS: A future release of the z/OS compiler may drop support for #pragma pack(packed). The equivalent is #pragma pack(1). Users should change #pragma pack(packed) to #pragma pack(1) in their code. Note that GCC for z/TPF supports #pragma pack(1). TPFDF APAR PK34634 makes corresponding changes to the TPF 4.1 product for #pragma pack(packed).However, that APAR does not need to be installed at the same time as this APAR. If TPF 4.1 users receive the pre-linker/linkage editor warning message "WARNING EDC4015: Unresolved references are detected: std::terminate()" when compiling and linking a C++ program, they should include the ./include/tpf/c_terminate.hpp header in their C++ program as follows: #ifdef __370__ #include <tpf/c_terminate.hpp> #endif Note that the ./include/tpf/c_terminate.hpp header is not needed for GCC and z/TPF, and this header does not exist in z/TPF.
