c012d80766 Fixing sacss failure introduced in changelist 183045. alignments are unpacked from varargs as promoted to size_t, but mps_pf_align is a naked number literal, and so was passed as int, causing a corrupt alignemnt failure in sacss.

6cedb9d2dc Correct pass_count to fail_count in testrun.bat. 
locbwcss shouldn't fail if there are non-contiguous allocations. Those are perfectly legitimate (MVFF uses CBS, which needs to allocate nodes in its splay tree).

9e2eef4fa0 Don't define _gnu_source if already defined. 
When using the build method of including the MPS directly into
one's own sources, that build system may already define _GNU_SOURCE
causing a warning here about re-defining it.

e88bcc5184 Document the intention behind mps_ld_isstale rather than the implementation: it captures the intention of testing whether a particular dependency is stale (even though the implementation in fact tests whether any dependency is stale). add new function mps_ls_isstale_any for expressing the intention of testing whether any dependencey is stale. the two functions have the same implementation at present, but the separation gives us the freedom to return a more precise result from mps_ld_isstale in future.
