+# AM_CHECK_IPHONE (ACTION_IF_FOUND, ACTION_IF_NOT_FOUND, [ACTION_IF_FAILED])
+# enables the "--with-iphone" flag; 
+# if the iPhoneSDK is detected, this will 
+#  - set the CC & CPP to the cross-compiler ( resp preprocessor)
+#  - as well as the apropriate CFLAGS, INCLUDES and LDFLAGS
+#  - these values can also be found in IPHONE_CC, IPHONE_CPP, 
+#    IPHONE_INCLUDES, IPHONE_ARCH, IPHONE_CFLAGS, IPHONE_LDFLAGS
+#  it will then call ACTION_IF_FOUND
+# elif ACTION_IF_FAILED is set and the iPhoneSDK is not detected even though the user
+#  requested it (by specifying a path, or simply saying "--with-iphone=yes"), 
+#  then ACTION_IF_FAILED is called
+# else 
+#  ACTION_IF_NOT_FOUND is called
+#
+# TODO: only run checks when architecture is right (x-compiling)
