# The variables above may be overridden by .../config/Makefile
# OTOPDIR is either TOPDIR or WINTOPDIR, whichever is appropriate for
#   arguments given to the OCaml compiler.
# CTOPDIR is either TOPDIR or WINTOPDIR, whichever is appropriate for
#   arguments given to the C and Fortran compilers.
# CYGPATH is the command that translates unix-style file names into
#   whichever syntax is appropriate for arguments of OCaml programs.
# DIFF is a "diff -q" command that ignores trailing CRs under Windows.
# CANKILL is true if a script launched by Make can kill an OCaml process,
#   and false for the mingw and MSVC ports.
# SORT is the Unix "sort" command. Usually a simple command, but may be an
#   absolute name if the Windows "sort" command is in the PATH.
# SET_LD_PATH is a command prefix that sets the path for dynamic libraries
#   (CAML_LD_LIBRARY_PATH for Unix, PATH for Windows) using the LD_PATH shell
#   variable. Note that for Windows we add Unix-syntax directory names in
#   PATH, and Cygwin will translate it to Windows syntax.
