# The probes.o file is necessary for dtrace support on Solaris, and on recent
# versions of systemtap.  (Older systemtap releases just produce an empty
# file, but that's okay.)  However, OS X's dtrace doesn't use it and doesn't
# even recognize the -G option.  So, build probes.o except on Darwin.
# This might need adjustment as other platforms add dtrace support.

# Make symlinks for these headers in the include directory. That way

#
# The point of the prereqdir incantation in some of the rules below is to
# force the symlink to use an absolute path rather than a relative path.
# For headers which are generated by make distprep, the actual header within
# src/backend will be in the source tree, while the symlink in src/include
# will be in the build tree, so a simple ../.. reference won't work.
# For headers generated during regular builds, we prefer a relative symlink.
