Subject: [PATCH] [PATCH 4/4] Avoid mis-identifying systems as SVR4
|
|
|
|
Linux can be misdetected as SVR4 because it has
|
|
libelf installed. This leads to linking with libelf, even though no
|
|
symbols from that library were actually used, and to a workaround for
|
|
a buggy getlogin() being enabled.
|
|
|
|
It is not documented which exact SVR4 system had the bug that the
|
|
workaround was added for, so all I could do is make an educated guess
|
|
at the #defines its compiler would be likely to set.
|
|
|
|
Modified from patch by Maarten ter Huurne.
