+# "extern inline" in traditional gcc means that the function should be 
+# inlined wherever it's seen, while in C99, "extern inline" means that i
+# the function should only be inlined where the inline definition is 
+# seen while in other places it's not inlined:
+# http://gcc.gnu.org/ml/gcc/2006-11/msg00006.html
+#
+# gmp checks "--std=gnu99" to use C99 convention however it internally 
+# defines some "extern inline" functions in gmp.h, which is included
+# by mainly .c files and finally lead a flood of redefinition function
+# errors when linking objects together.
+#
+# So disable C99/ANSI detection to stick to tranditional gcc behavior
