* fixinc/inclhack.def
|
||||
(AAB_svr4_replace_byteorder): added. Takes advantage of GCC features
|
||||
(unixware7_byteorder_fix): added. Removes conflicts for new defs
|
||||
in net/inet.h.
|
||||
(svr5_mach_defines): added. Like svr4_mach_defines, with new syntax
|
||||
(svr4_endian): enabled with SVR5
|
||||
(svr4_mkdev): simplified syntax and enabled with SVR5
