+# http://in3www.epfl.ch/~schaffne/linux-2.4-bsd-expr.patch
+The following makes it possible to compile linux 2.4.19 to 2.4.25 on Mac OS X,
+where "expr" doesn't understand the "length" construct
+(which it doesn't have to, according to SuSv3
+(see http://www.opengroup.org/onlinepubs/007904975/utilities/expr.html)
+See also http://sources.redhat.com/ml/crossgcc/2004-02/msg00131.html

+  expr: syntax error
+  KERNELRELEASE "2.4.21" exceeds 64 characters
