A pretty trivial example causes the problem for me:

bash-2.05$ ls
Makefile.am   configure.in  foo.c
bash-2.05$ cat configure.in
AC_INIT(foo.c)

AM_INIT_AUTOMAKE(libfoo, 0.0.0)
AC_PROG_LIBTOOL

AC_OUTPUT(Makefile)
bash-2.05$ cat Makefile.am
lib_LTLIBRARIES = libfoo.la

libfoo_la_SOURCES = foo.c
bash-2.05$ cat foo.c
void foo() {

}
bash-2.05$ libtoolize --force --copy
You should add the contents of `/usr/freeware/share/aclocal/libtool.m4'
to `aclocal.m4'.

It looks like the offending sed command is being requoted and escaped
differently on IRIX than it is on Linux.

IRIX:

test "${lt_cv_global_symbol_to_c_name_address+set}" = set ||
lt_cv_global_symbol_to_c_name_address='sed -n -e '\''s/^\'^: \([^\'^
]*\) $/  {\"\1\", (lt_ptr) 0},/p'\'' -e '\''s/^\'^[BCDEGRST] \([^\'^
]*\) \([^\'^ ]*\)$/  {"\2", (lt_ptr) \&\2},/p'\'

Linux:

test "${lt_cv_global_symbol_to_c_name_address+set}" = set ||
lt_cv_global_symbol_to_c_name_address='sed -n -e '\''s/^: \([^ ]*\) $/
{\"\1\", (lt_ptr) 0},/p'\'' -e '\''s/^[BCDEGRST] \([^ ]*\) \([^ ]*\)$/
{"\2", (lt_ptr) \&\2},/p'\'''

Note the \'^ that is getting added to the IRIX version after /^ and
after [^, and the two ' missing from the end of the IRIX version.

In both cases, the line in aclocal.m4 that creates the above lines in
config.cache are:

lt_cv_global_symbol_to_c_name_address="sed -n -e 's/^: \([[^ ]]*\) $/
{\\\"\1\\\", (lt_ptr) 0},/p' -e 's/^$symcode \([[^ ]]*\) \([[^ ]]*\)$/
{\"\2\", (lt_ptr) \&\2},/p'"

Can you reproduce this?

When I invoke configure, what tool in the chain does the requoting and
escaping of the above line from aclocal.m4?

Thanks.
