I guess it is not that easy: If the pragma is available the definition is made as
described in
  http://docs.oracle.com/cd/E19205-01/819-5265/bjacu/index.html
The header basically means "use always get pagesizes2 where getpagesizes is used".
It does not look like it is possible to revert this. It may be necessary to use a custom
header first or one from an older Solaris release matching the older SUNW linker contract.
