>Description:
Instead of all the header files including value.h and then using value_ptr, have them define an opaque ``struct value'' and use that.

Somewhat mysteriously the need for this is highlighted by the HPUX port.  It runs into some bad include header confusion that is made worse by value.h being included too early.
