Subject: Some platforms (most notably Windows) do not have a $HOME by default.
X-Git-Tag: OpenSSL_0_9_6c~182^2~205
X-Git-Url: https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=f0b54fefe9bf7845ca8d2c137f1f5483ac17320c;hp=cf2d9e09b3b0bd0f156ed3831bf6c47b43d3cfc8

Some platforms (most notably Windows) do not have a $HOME by default.
For those, unless the environment variables RANDFILE or HOME are
defined (the default case!), RAND_file_name() will return NULL.
This change adds a default HOME for those platforms.

To add a default HOME for any platform, just define DEFAULT_HOME in
the proper place, wrapped in appropriate #ifdef..#endif, in e_os.h.
