+dnl AC_MULTILIB creates a variable libdirsuffix, containing

+[
+ dnl There is no formal standard regarding lib and lib64. The current
+ dnl practice is that on a system supporting 32-bit and 64-bit instruction
+ dnl sets or ABIs, 64-bit libraries go under $prefix/lib64 and 32-bit
+ dnl libraries go under $prefix/lib. We determine the compiler's default
+ dnl mode by looking at the compiler's library search path. If at least
+ dnl of its elements ends in /lib64 or points to a directory whose absolute
+ dnl pathname ends in /lib64, we assume a 64-bit ABI. Otherwise we use the
+ dnl default, namely "lib".
