--- Comment #8 from Austin English austinenglish@gmail.com 2009-01-18 16:25:15 --- Looks like Cygwin is missing several header files: configure:7941: checking for net/if_arp.h configure:7974: gcc -c -g -O2 conftest.c >&5 conftest.c:84:24: net/if_arp.h: No such file or directory
(along with some of the other net/*,netinet* heaers).
Might compare your results on cygwin to linux to see what you're missing/needing.
