recommended sequence to add libtool to an existing configure.ac

[Ed Mansky]

Hi

I am trying to add libtool functionality to an existing configure.ac 
script so that the package will have the usual enable shared/static 
options and support for threaded libraries, especially pthread.

I am using autoconf 2.69 and automake 1.14 on OSX Darwin 8.11.0 w/gcc 
4.3.3 and GNU make 4.0

The reason I am doing this is because the existing configure script 
of this package did not find my pthread library in /usr/lib and it 
currently makes no use of libtool at all.

I have run other configure scripts that did find my pthread library.

I did the following in sequence:

1) Ran autoscan against the directory tree of the package. I added 
the missing macros to the existing configure.ac script that the 
autoscan result suggested.

2) Added LT_INIT to configure.ac

3) Ran autoreconf --install

Is this the recommended sequence to add correctly libtool 
functionality to an existing configure.ac ?

I thought it would be better to add libtool functionality via the 
correct macros to configure.ac, rather than hack at the configure 
script directly.

Any tips or ideas would be greatly appreciated.

Thanks,
