  # Fix use of min/max with clang
  patch :DATA

  def install
    system "./configure", "--disable-debug",
                          "--prefix=#{prefix}",

# Changes included in this patchset:
# 1) Explicitly use clang/clang++ in Makefile
# 2) __min() and __max() macros break bon_csv2html.cpp: "redefinition of 'min' as different kind of symbol"
#    Remove the construct in favor of macro targets min()/max() provided by the library
#    Files affected: port.h.in port.h duration.cpp bonnie++.cpp
# 3) Remove the #ifdef _LARGEFILE64_SOURCE macros which not only prohibits the intended functionality of
#    splitting into 2 GB files for such filesystems but also incorrectly tests for it in the first place.
#    The ideal fix would be to replace the AC_TRY_RUN() in configure.in if the fail code actually worked.
#    Files affected: bonnie++.cp
