While compiling net_db.c from Guile 2.0.12 with MinGW, I get a bunch
of warnings such as this one:
net_db.c:454:20: warning: 'sym_ai_passive' defined but not used [-Wunused-variable]
SCM_VARIABLE_INIT (sym_ai_passive, "AI_PASSIVE",
^
../libguile/snarf.h:82:29: note: in definition of macro 'SCM_SNARF_HERE'
# define SCM_SNARF_HERE(X) X
^
net_db.c:454:1: note: in expansion of macro 'SCM_VARIABLE_INIT'
SCM_VARIABLE_INIT (sym_ai_passive, "AI_PASSIVE",
^
AFAICT, these SCM_VARIABLE_INIT calls wind up declaring static
variables that are not used in net_db.c. Is that what's supposed to
happen, or do I need to look more into this? Do people get these
warnings on Posix platforms?

Oddly I don't get these warnings, but perhaps I should. I reworked this
file to not create these variables. Thanks for the report :)

Which version of GCC do you use? I have 5.3.0 here, and its quite
picky, given the warning options we use.
