Comment (by macportsraf):

 I'm now seeing the same problem on 10.4. I can't successfully install
 apple-gcc42 because of this legacy-support failure. And I can't compile a
 local copy of legacysupport because there's no system copyfile.h file.

 And I think this is a big problem. Even if the `__asm` renaming worked to
 rename the `__mpls_libc_*` functions to their underlying system functions,
 it was all assuming that all of these functions used one of the aliasing
 macros (`__DARWIN_ALIAS`, `__DARWIN_ALIAS_I`, `__DARWIN_INODE64`), but on
 10.4 two of the functions don't use an aliasing macro.

 So even if things were working as I expected them to, the `readdir` and
 `readdir_r` functions wouldn't be able to work.

 But the `__asm` renaming isn't working as I expected it to so there's more
 to it.

 We might need to revert to a macro-based implementation rather than an
 `__asm` renaming-based implementation.

 I'll bring this up at https://github.com/macports/macports-legacy-
 support/pull/62
