MacOS X nested functions in libtool library

[Bill Northcott]

I am trying to build a libtool library containing nested functions on  
MacOS X Intel.

The project is using Autoconf 2.59, Automake 1.9.6 and Libtool 1.5.22.

Adding '-fnested-functions' to the CFLAGS stops the compiler  
barfing.  However as per Apple Tech note http://developer.apple.com/ 
technotes/tn2006/tn2161.html it is also necessary to add -fnested- 
functions or an equivalent ld flag to the compiler link command.   
Without this flag, the linker defaults to disable_stack_execute on  
i386 and the library crashes at runtime.

Adding -fnested-functions to libfoo_la_LDFLAGS does not work because  
libtool strips it out before invoking gcc.

Is there a way around this or an actual fix?

Thanks
