[AC21.5] Remove call to non-working -fno-gnu-linker

This combines yesterday's 2 proposed patches for configure: removing the non-working -fno-gnu-linker call from gcc under Solaris 5.5 and below and also replaces 'head -1' 'with sed 1q'. xemacs-21.5/ChangeLog addition: 2005-03-23 Vin Shelton <acs(a)xemacs.org&gt; * configure.in: Remove -fno-gnu-linker option from Solaris dynodump builds; it doesn't do anything. Don't use 'head -1' - it's deprecated by coreutils-5.3.0 on some platforms. 21.5 source patch: Diff command: cvs -q diff -u Files affected: configure.ac Index: configure.ac =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/configure.ac,v retrieving revision 1.4 diff -a -u -u -r1.4 configure.ac --- configure.ac 2005/03/15 12:37:14 1.4 +++ configure.ac 2005/03/24 00:53:25 ＠＠ -2302,8 +2302,6 ＠＠ *86* ) dynodump_arch=i386 ;; powerpc ) dynodump_arch=ppc ;; esac - dnl Dynodump requires the system linker - test "$GCC" = "yes" && XE_APPEND(-fno-gnu-linker, ld_switch_site) fi dnl Feed s&m crud to src/Makefile ＠＠ -2359,12 +2357,12 ＠＠ dnl run through the AC_PROG_CC mill. dnl Would anybody really build libsrc with GCC and XEmacs with non-GCC? if test "$GCC" = "yes"; then - compiler_version=`$XEMACS_CC --version | head -1` - gcc_compiler_specs=`$XEMACS_CC -v 2>&1 | sed 's/.* \([[^ ]]\)/\1/' | head -1` + compiler_version=`$XEMACS_CC --version | sed 1q` + gcc_compiler_specs=`$XEMACS_CC -v 2>&1 | sed 's/.* \([[^ ]]\)/\1/' | sed 1q` else case "$XEMACS_CC" in dnl The Intel cc compiler ic*) - compiler_version=`icc -V 2>&1 | head -1` + compiler_version=`icc -V 2>&1 | sed 1q` ;; dnl non-gcc machine-specific magic - contributions welcome *) case "$ac_cv_build" in ＠＠ -2393,7 +2391,7 ＠＠ ;; *-*-solaris*) - compiler_version=`$XEMACS_CC -V 2>&1 | head -1` + compiler_version=`$XEMACS_CC -V 2>&1 | sed 1q` ;; alpha*-dec-osf*)
