unsetenv(3) returns int, not void
This compatilibity implementation has been returning a wrong type, ever since 731043fd (Add compat/unsetenv.c ., 2006-01-25) added to the system, yet nobody noticed it in the past 16 years, presumably because no code checks failures in their unsetenv() calls. Sigh. For now, make it always succeed. Signed-off-by: Junio C Hamano <gitster@pobox.com>
