The attached branch fixes some (maybe all) of the sparc-specific build failure issues in libexplain's own source:

    - open_flags.c: #ifdef guard more flags (O_FSYNC, FFSYNC, O_ASYNC, FFASYNC)
    - readv.c/writev.c: fix misuse of size_t to avoid fatal compiler warnings

However, a problem in the libc6 <bits/fcntl.h> header (LP: #517212) still prevents libexplain from compiling. That header file problem also (coincidentally) results in the error 'O_FSYNC' undeclared -- but a few lines later. Note that this new failure is actually the result of an improper definition of FFSYNC to O_FSYNC in the fcntl.h header which tricks libexplain despite the correct #ifdef guards in the patched libexplain.

Therefore, this package cannot compile on sparc until LP: #517212 gets resolved.
