Inherit from GCC_3.4 and declare __enable_execute_stack. * mklibgcc.in (lib2funcs): Add _enable_execute_stack. * config/netbsd.h (NETBSD_ENABLE_EXECUTE_STACK): ANSIfy. * config/sol2.h (TRANSFER_FROM_TRAMPOLINE): Rename into ENABLE_EXECUTE_STACK. * config/alpha/alpha.c (alpha_initialize_trampoline): Conditionalize on ENABLE_EXECUTE_STACK instead of TRANSFER_FROM_TRAMPOLINE. * config/alpha/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Rename into ENABLE_EXECUTE_STACK. * config/alpha/osf.h (TRANSFER_FROM_TRAMPOLINE): Likewise. * config/i386/i386.c (x86_initialize_trampoline): Conditionalize on ENABLE_EXECUTE_STACK instead of TRANSFER_FROM_TRAMPOLINE. * config/i386/netbsd-elf.h (TRANSFER_FROM_TRAMPOLINE): Rename into ENABLE_EXECUTE_STACK. * config/i386/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Likewise. * config/i386/netbsd64.h (TRANSFER_FROM_TRAMPOLINE): Likewise. * config/sparc/freebsd.h (TRANSFER_FROM_TRAMPOLINE): Likewise. * config/sparc/netbsd-elf.h (TRANSFER_FROM_TRAMPOLINE): Likewise. * config/sparc/sparc.c (sparc_initialize_trampoline): Conditionalize on ENABLE_EXECUTE_STACK instead of TRANSFER_FROM_TRAMPOLINE. (sparc64_initialize_trampoline): Likewise. * doc/tm.texi (trampolines): Add ENABLE_EXECUTE_STACK macro.
