+Subject: [PATCH] configure.ac: fixup LFS check for autoconf-2.72
+
+There are two problems with the check:
+1) The 'unknown' case has a problem which is rejected by stricter C compilers
+because it has -Wimplicit-int and -Wimplicit-function-declaration warnings. Fix that.
+
+2) For the 'other' case, we were using the value of ac_cv_sys_file_offset_bits for
+-D_FILE_OFFSET_BITS to pass down into the Perl module build, but autoconf-2.72
+drops the use of ac_cv_sys_file_offset_bits in cf09f48841b66fe76f606dd6018bb3a93242a7c9,
+so this ends up defining '-D_FILE_OFFSET_BITS=' which then breaks the build.
+
+I've added a hack for 2) to preserve the old behavior.
