-#NUMBER= -DLUA_NUM_TYPE=double
-#NUMBER= -DLUA_NUM_TYPE=float

+# --------------------------------------------------------------- Lua libraries
+
+# Support for dynamically loading C libraries for Lua is a very important
+# feature, which we strongly recommend be enabled. By default, this support is
+# enabled on Windows systems (see below) but disabled on other systems because
+# it relies on system-dependent code that is not part of ANSI C. For more
+# information on dynamic loading, read the comments in src/lib/liolib.c .
+#
+# To enable support for dynamic loading on Unix systems that support the dlfcn
+# interface (e.g., Linux, Solaris, IRIX, BSD, AIX, HPUX, and probably others),
+# uncomment the next two lines.
+#
+#LOADLIB= -DUSE_DLOPEN=1
+#DLLIB= -ldl
+#
+# In Linux with gcc, you should also uncomment the next definition for
+# MYLDFLAGS, which passes -E (= -export-dynamic) to the linker. This option
+# allows dynamic libraries to link back to the `lua' program, so that they do
+# not need the Lua libraries. (Other systems may have an equivalent facility.)
+#
+#MYLDFLAGS= -Wl,-E
+#
+# On Windows systems. support for dynamic loading is enabled by default.
+# To disable this support, uncomment the next line.
+#
+#LOADLIB= -DUSE_DLL=0
+
+# The Lua IO library (src/lib/liolib.c) has support for pipes using popen and
+# pclose. This support is enabled by default on POSIX systems.
+# If your system is not POSIX but has popen and pclose, define USE_POPEN=1.
+# If you don't want to support pipes, define USE_POPEN=0.
+#
+#POPEN= -DUSE_POPEN=1
+#POPEN= -DUSE_POPEN=0
+#
+# The form below will probably work in (some) Windows systems.
+#
+#POPEN= -DUSE_POPEN=1 -Dpopen=_popen -Dpclose=_pclose
+
+# The Lua OS library (src/lib/liolib.c) exports an interface to the C function
+# tmpnam, which gcc now thinks is `dangerous'. So, support for tmpnam is
+# disabled by default when compiling with gcc.
+# If you still want to use tmpnam, define USE_TMPNAME=1. If you don't want to
+# use tmpnam even if you're not compiling with gcc, define USE_TMPNAME=0.
+#
+#TMPNAM= -DUSE_TMPNAME=1
+#TMPNAM= -DUSE_TMPNAME=0
+
+# The Lua math library (src/lib/lmathlib.c) now operates in radians, unlike
+# previous versions of Lua, which used degrees. To use degrees instead of
+# radians, define USE_DEGREES.
+#
+#DEGREES= -DUSE_DEGREES
+
+# ------------------------------------------------------------------ Lua core
+
+# Lua uses double for numbers. To change this, uncomment and edit the following
+# line, changing USE_XXX to one of USE_DOUBLE, USE_FLOAT, USE_LONG, USE_INT.
+#
+#NUMBER= -DLUA_USER_H='"../etc/luser_number.h"' -DUSE_XXX
+
+# When compiling Lua with gcc on a Pentium machine, using a fast rounding
+# method for the conversion of doubles to ints can give around 20% speed
+# improvement. To use this rounding method, uncomment the following line.
+#NUMBER= -DLUA_USER_H='"../etc/luser_number.h"' -DUSE_FASTROUND
+
+# For partial compatibility with old upvalue syntax, define LUA_COMPATUPSYNTAX.
+# For partial compatibility with old upvalue behavior in C functions, define
+# LUA_COMPATUPVALUES. Add these definitions to MYCFLAGS.

+#
+EXTRA_LIBS= -lm
 
-# If you need compatibility with previous versions, edit and uncomment the
-# definition of COMPAT below.
-# Use -DLUA_COMPAT_READPATTERN if you need complex read patterns.
-# Use -DLUA_COMPAT_ARGRET if you need the old semantics that used only the
-# first value returned by a function when it is called as the last parameter.
-# Use -DLUA_DEPRECATEDFUNCS if you need the obsolete functions in the standard 
-# Lua library (not recommended).
-#COMPAT= -DLUA_COMPAT_READPATTERN -DLUA_COMPAT_ARGRET -DLUA_DEPRECATEDFUNCS
+# If you want to customize the stand-alone Lua interpreter, uncomment and
+# edit the following two lines; also edit etc/saconfig.c to suit your needs.

+# to EXTRA_LIBS.
