From 325391aef90a8b1cfbf8c5980a4f15d602b9e72c Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Thu, 31 Jan 2002 07:53:20 +0000 Subject: [PATCH] Albert Chin: Forgot one case. On HP-UX 11.00, gethostbyname_r() is properly defined if -D_REENTRANT is used. Without it, the compiler still accepts the function prototype but gives a warning about hostent_data going out of scope. This is because struct hostent_data is not declared. So, we force an error by trying to set a variable to the struct. --- acinclude.m4 | 2 ++ 1 file changed, 2 insertions(+) diff --git a/acinclude.m4 b/acinclude.m4 index e4a37913e..3b7ab69f0 100644 --- a/acinclude.m4 +++ b/acinclude.m4 @@ -377,6 +377,7 @@ AC_DEFUN(CURL_CHECK_GETHOSTBYNAME_R, int gethostbyname_r(const char *, struct hostent *, struct hostent_data *);],[ +struct hostent_data data; gethostbyname_r(NULL, NULL, NULL);],[ AC_MSG_RESULT(yes) AC_DEFINE(HAVE_GETHOSTBYNAME_R_3) @@ -394,6 +395,7 @@ gethostbyname_r(NULL, NULL, NULL);],[ int gethostbyname_r(const char *,struct hostent *, struct hostent_data *);],[ +struct hostent_data data; gethostbyname_r(NULL, NULL, NULL);],[ AC_MSG_RESULT(yes) AC_DEFINE(HAVE_GETHOSTBYNAME_R_3)
