I have a mix of PA-RISC 1.1 and 2.0 processors and am continually having to manually add +DAportable to compile flags in order to get binaries to run on both kinds of machines (since I compile on a PA-RISC 2.0 machine).
Is there some reason this is not currently added by autoconf? I did not find anything apropos in the mailing list archives.
The IBM AIX compilers do the equivalent of +DAportable by default. For HP, you have to tell the compiler to produce a binary that will run on various kinds of processors. -- Joe Buehler
