USRSTACK macro

I'm upleveling code from 10.20 to 11.11....but I'm running into a problem in which the USRSTACK macro does not seem to be defined in 11.11. Has anybody else experienced this/fixed it/worked around it? Is there a different macro I should be using instead?

Thanks for any info you can provide!!

HP-UX 11 supports 64 bit mode. Programs can be either SOM or ELF. This is why macros like that vanished. Using such a macro is non-portable. There really is no guarantee that a object called a "stack" will exist. About the best you could do is take the address of the first automatic variable.
