[gpsd-dev] [PATCH v2 1/1] gps2udp: reset errno after getaddrinfo call

[Ferry Huberts]

From: Ferry Huberts <address@hidden>

It returns errno==2 ("No such file or directory") when the program
is run as "LD_LIBRARY_PATH=. ./gps2udp -n -u 224.0.0.224:2240"
in the source directory.

The observed effect was that the port number conversion considered
a perfectly valid port number as invalid.
