## configure for glibc2 with DES crypt(), if you have glibc-crypt-2.x.tar.gz.
## To use this, drop glibc-crypt-2.x.tar.gz into the current directory,
## uncomment these lines, comment out the lines above to build the library
## without DES crypt(), and rebuild the library with 'sh COMPILE'.
##
## If you can find a glibc-crypt based /usr/include/crypt.h and
## /lib/libcrypt-2.*.so you can simply copy them to your /lib and
## /usr/include, and then things linked with the standard (MD5) crypt()
## that comes with glibc2 will be able to use either MD5 or DES.
