# The following are written to make sure the build fails if the output file
# already exists, and cannot be overwritten. For example, if we have
# pdf/gprbuild_ug.pdf open in a browser on windows, the $(MAKE_PDF) command
# will complain:
# cp: cannot create regular file `.../gprbuild_ug.pdf': Device or resource busy
# but still returns a zero (successful) exit status. Therefore, we delete the
# output first, so the ${RMDIR} will correctly return a non-zero status.
# But if pdf does not exist, then the ${RMDIR} command will incorrectly fail;
# therefore, we do ${MKDIR} first -- hence we do ${MKDIR} twice, which is a bit
# odd, but successfully works around the bug in $(MAKE_PDF) (i.e. texi2pdf).
