So in summary, we can't have __attribute__((weak,alias("PMPI_..."))) in the header because:

1. it does not compile with gcc

It also does not compile with the new version of clang. conftest.c:37:34: error: alias must point to a defined variable or function int foo(void) __attribute((weak, alias("__foo"))); ^

2. it breaks PMPI interposition with clang 3. it breaks -fvisibility=hidden with clang
