Thanks for spotting this. Will change to
case $arg in *.o | *.lo | *.a)
Re the two other bug reports. If I recall correctly, the current
version of ldAIX4 was provided by Tom Vogels a long time ago. Not sure
if R Core members currently still have access to an AIX4 system ...
I see that Tcl/Tk has a script called ldAix which I think does something
similar and hard-wires nm to /usr/ccs/bin/nm, and that libtool has
# If we're using GNU nm, then we don't want the "-C" option.
# -C means demangle to AIX nm, but means don't demangle with GNU nm
if $NM -V 2>&1 | grep 'GNU' > /dev/null; then
_LT_AC_TAGVAR(export_symbols_cmds, $1)='$NM -Bpg $libobjs $convenience | awk '\''{ if (((\[$]2 == "T") || (\[$]2 == "D") || (\[$]2 == "B")) && ([substr](\[$]3,1,1) != ".")) { print \[$]3 } }'\'' | sort -u > $export_symbols'
else
_LT_AC_TAGVAR(export_symbols_cmds, $1)='$NM -BCpg $libobjs $convenience | awk '\''{ if (((\[$]2 == "T") || (\[$]2 == "D") || (\[$]2 == "B")) && ([substr](\[$]3,1,1) != ".")) { print \[$]3 } }'\'' | sort -u > $export_symbols'
fi
As the libtool configure code is run anyway, I'd prefer making the $NM
configure value available and testing its value for being GNU nm or not,
if possible. But see above: do you have a fix to the current version of
ldAIX4 that works with GNU nm?
