Ok, downloaded and configured as usual. GnuTLS compiles out of the box 
and make check is successful (no errors!).

I don't want to be a perfectionist but I am listing the few very minor 
issues.


1) a warning realted to vasprintf (an old friend , isn't it?)

/bin/sh ../libtool --tag=CC   --mode=compile gcc -std=gnu99 
-DHAVE_CONFIG_H -I. -I..  -DLOCALEDIR=\"/usr/local/share/locale\" -I../lgl

gnutls_str.c: In function '_gnutls_string_append_printf':
gnutls_str.c:238: warning: implicit declaration of function 'vasprintf'


2) A warning related to inet_pton. In a previous e-mail you said

> Problem in gnulib, I'll see if I can get these fixed.  I don't think
> this is important though.

I usually think that an implicit declaration is always dangerous, but 
you are the expert!

/bin/sh ../../libtool --tag=CC   --mode=compile gcc -std=gnu99 
-DHAVE_CONFIG_H -I. -I../..  -I../../includes -I../../includes -I../../l
gl -I../../lgl -I../../gl -I../../gl -I/usr/local/include -pipe

tcp.c: In function 'tcp_connect':
tcp.c:41: warning: implicit declaration of function 'inet_pton'

This warnig appears in some other files.

3)  A warning about 'setsockopt'.
In a previous e-mail you said

> Probably a buggy system header file, the argument should be 'void*'
> which should be castable from any type.

Uhm... in the MSDN documentation the 4th argument is  const char* and in 
MinGW  setsockopt  is in
winsock.h,winsock2.h and ws2spi.h. In all includes the 4th argument is 
const char*. May be in some other platform is void * but in Windows I 
think is definitively const char *.

ex-serv-export.c: In function 'main':
ex-serv-export.c:182: warning: passing argument 4 of 'setsockopt' from

4) several

libtool: link: warning: `-no-install' is ignored for i686-pc-mingw32
libtool: link: warning: assuming `-no-fast-install' instead

We can ignore those..


Hope this helps
