Would you believe that I wrote all of this on a Mac? I just happen to be not using HFS for the partition I did this work on. Oops :) config/ac-macros/alloca.m4: mvdir config/ac-macros/character_sets.m4: mvdir config/ac-macros/check_cpu.m4: mvdir config/ac-macros/compiler_flag.m4: mvdir config/ac-macros/ha_archive.m4: mvdir config/ac-macros/ha_berkeley.m4: mvdir config/ac-macros/ha_example.m4: mvdir config/ac-macros/ha_innodb.m4: mvdir config/ac-macros/ha_isam.m4: mvdir config/ac-macros/ha_ndbcluster.m4: mvdir config/ac-macros/ha_tina.m4: mvdir config/ac-macros/large_file.m4: mvdir config/ac-macros/misc.m4: mvdir config/ac-macros/mysqlfs.m4: mvdir config/ac-macros/openssl.m4: mvdir config/ac-macros/readline.m4: mvdir config/ac-macros/sanity.m4: mvdir config/ac-macros/zlib.m4: mvdir configure.in: Fix silly little problem with case insensitive filesystems. Funny thing is that I wrote all this on a Mac, but I don't use HFS on that partition so I never noticed that it would be an issue. Oops :)
