Folks,
I did some digging on our toolchain here on our new Yellowdog 4.0 installed machines. They have a 3.3.2 compiler on them by default, apparently.
As someone else discerned, that cause an issue with the dummy() function being static in the stubs.o file for the examples directory.
I've found that all appears to be better if the test in the example/stubs.c file is changed from:
#if GCC_VERSION < 3004 to #if GCC_VERSION < 3003
(BTW, the GCC_VERSION symbol, google revealed, comes from ansidecl.h. Oh yeah.)
I'm not sure of the generality of this fix, so I am reluctant to submit a direct patch for it. Perhaps someone more familiar with the details of either the YDL 4.0 or GCC 3.3 vs 3.4 releases can speak authoritatively on this issue.
HTH, jdl
