that you can influence which definitions you get by setting the
WINVER symbol before including these two files. For example,
getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
- symbol is set indiriectly through WINVER). You can set this by
+ symbol is set indirectly through WINVER). You can set this by
adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
code may not run on older Windows releases then. My Windows 2000
box was not able to run the code, for example. The situation is
suggests that getaddrinfo should be available on all Windows
