Sync s/ files with GNU 23.1.92, delete obsolete stuff, simplify other stuff --- ChangeLog 2010-02-20 Ben Wing <ben@xemacs.org> * configure: * configure.ac (XE_EXPAND_VARIABLE): * configure.ac (TAB): irix6-0.h renamed to irix6-5.h; sco7.h deleted. bsd4-3.h renamed to bsd-common.h. Simplify setting machine= for intel386, mips. Put back linux.h. Incorporate some stuff about debug/optimization flags in irix6-5.h into configure.ac. Add a comment about LCC stuff with optimization flags that should be fixed up. --- src/ChangeLog 2010-02-20 Ben Wing <ben@xemacs.org> * sysdep.c: * sysdep.c (qxe_reliable_signal): * sysdep.c (retry_open_1): * sysdep.c (retry_close): * sysdep.c (retry_read_1): * sysdep.c (retry_write_1): * sysdep.c (retry_fopen): * sysdep.c (retry_fclose): * sysdep.c (retry_fread): * sysdep.c (retry_fwrite): Remove conditionalization on INTERRUPTIBLE_IO, INTERRUPTIBLE_OPEN, INTERRUPTIBLE_CLOSE -- always check for EINTR as there's no harm in it. Remove old #if 0'ed out SA_RESTART code. Use manifest constant IRIX6_5 instead of IRIX. * Makefile.in.in: * dired.c: * dired.c (Ffile_attributes): Use manifest constant IRIX6_5 instead of IRIX. Eliminate constant BSD4_2, use BSD4_3 instead. * getloadavg.c: * getloadavg.c (getloadavg): * getloadavg.c (LDAV_PRIVILEGED): * getloadavg.c (LDAV_DONE): Sync with GNU 23.1.92. 2010-02-20 Ben Wing <ben@xemacs.org> * s/README: * s/aix4-2.h: * s/aix4-2.h (MAIL_USE_LOCKF): * s/bsd-common.h: * s/freebsd.h: * s/freebsd.h (Carey): * s/freebsd.h (or): * s/gnu.h: * s/gnu.h (DATA_START): * s/hpux11-shr.h: * s/hpux11.h: * s/hpux11.h (random): * s/irix6-5.h: * s/linux.h: * s/mach-bsd4-3.h: * s/netbsd.h: * s/netbsd.h (or): * s/netbsd.h (A_TEXT_OFFSET): * s/netbsd.h (NO_MATHERR): * s/openbsd.h: * s/sol2.h: * s/usg5-4-2.h: * s/usg5-4.h: * s/usg5-4.h (or): * s/usg5-4.h (ORDINARY_LINK): Sync with GNU 23.1.92. Put back linux.h. Rename: bsd4-3.h -> bsd-common.h; irix6-0.h -> irix6-5.h. Delete: template.h (useless). Delete a whole bunch of obsolete stuff in sol2.h, linux.h, freebsd.h -- assume anything over 10 years old is sufficiently obsolete to be deleted. Remove LIBS_DEBUG, C_DEBUG_SWITCH, C_OPTIMIZE_SWITCH, KERNEL_FILE, LDAV_SYMBOL, most remaining PTY stuff, remaining TERMINFO/TERMCAP stuff. Update README appropriately. Remove stuff in hpux11-shr.h duplicated in hpux11.h. Remove sco7.h, identical with usg5-4-2.h. Remove unused POSIX flag, BROKEN_TIOC*, NO_SIOCTL_H. 2010-02-20 Ben Wing <ben@xemacs.org> * m/arm.h: * m/hp800.h: * m/intel386.h: * m/mips.h: * m/powerpc.h: * m/sparc.h: * m/template.h: Temporarily ifdef out all defines involving load-average stuff -- using define ENABLE_SM_FILE_DECLS_OF_LOADAVG_STUFF, which is not defined. I'm pretty sure getloadavg.c will take care of defining stuff properly on all systems without the need to duplicate the info in m/*. --ben Delete LIBS_TERMCAP; configure auto-handles this. Delete extra stuff in hp800.h. Delete C_DEBUG_SWITCH, C_OPTIMIZE_SWITCH, LDAV_SYMBOL; incorporate some stuff into configure.ac.
