In fact it seems to come from line 6202/6203 in libltdl/config/ltmain.m4sh:
6194 if ${skipped_export-false}; then
6195 func_echo "generating symbol list for \`$libname.la'"
6196 export_symbols="$output_objdir/$libname.exp"
6197 $opt_dry_run || $RM $export_symbols
6198 libobjs=$output
6199 # Append the command to create the export file.
6200 test -z "$concat_cmds" || concat_cmds=$concat_cmds~
6201 eval concat_cmds=\"\$concat_cmds$export_symbols_cmds\"
6202 if test -n "$output"; then
6203 eval concat_cmds=\"\$concat_cmds~\$RM $last_robj\"
6204 fi
6205 fi
Do we want to delete $output or $last_robj?
Cheers,
Patrick
