[Qemu-devel] [PULL 52/65] slirp: replace a DEBUG block with WITH_ICMP_ERROR_MSG

[Samuel Thibault]

From: Marc-André Lureau <address@hidden>

icmp_send_error() doesnt actually log messages when DEBUG is enabled.
Let's use a different define that describes better the tweaked
behaviour of the function, and avoid uncompiled code.
