There is no limit in bash or Cygwin, as far as I know (just
successfully tested up to 13,598,720 bytes in 1.7).   However, if you
export the variable to the environment and expect it to be visible to
a Windows program using GetEnvironmentVariable(), then there is (or at
least used to be) a hard length limit of 32,766 characters (32,767
including the trailing NUL).
