CVS commit: src/tools/compat

["Alan Barrett" <apb%netbsd.org@localhost>]

Module Name:    src
Committed By:   apb

Modified Files:
        src/tools/compat: compat_defs.h

Log Message:
Clarify the NetBSD-specific and Linux-specific code at the top of
compat_defs.h:

* Explain why _NETBSD_SOURCE should not be defined on NetBSD.
* Move NetBSD-specific block to the top of the file.
* Improve comment about Linux <feature.h>.
* Move #undef _POSIX_SOURCE and #undef _POSIX_C_SOURCE to the
  Linux-specific block instead of a place that would affect all
  non-NetBSD platforms.  This makes the code match the comment.

This will need to be re-visited if other platforms also need
#undef _POSIX_SOURCE or #undef _POSIX_C_SOURCE.  At present, I suspect
that they are needed only for Linux.
