Hi,
as you might have seen from my commits during last days I've tried to
get the examples compiled with MinGW, and specially also MinGW64.

Currently I get those warnings with 64-bit:

anyauthput.c: In function 'read_callback':
anyauthput.c:95: warning: format '%d' expects type 'int', but argument 3
has type 'size_t'
...

has type 'size_t'
...

...

ftp-wildcard.c: In function 'main':
ftp-wildcard.c:70: warning: call to
'_curl_easy_setopt_err_write_callback' declared with attribute warning:
curl_easy_setopt expects a curl_write_callback argument for this option

for the size_t format warnings I've no real good idea; inttypes.h has no
PRI* macro for size_t, so if we go that way we would have to add an own
macro like CURL_FORMAT_SIZE_T to curlbuild.h[dist] which depends on
platform/arch so that we can properly build up format strings for
printing size_t (I would prefer this); otherwise we could add uint_64
casts to all size_t printfs ...

then the remaining warnings seem to come from typecheck-gcc.h, and those
make me believe that these checks either dont act properly with 64-bit,
or things are missing; I tested on 64-bit Linux and get same warnings
with certinfo.c, ftp-wildcard.c, multi-debugcallback.c:

anyauthput.c: In function ‘read_callback’:
anyauthput.c:95: warning: format ‘%d’ expects type ‘int’, but argument 3
has type ‘size_t’

certinfo.c: In function ‘main’:

multi-debugcallback.c:135: warning: call to
‘_curl_easy_setopt_err_debug_cb’ declared with attribute warning:

l_debug_callback argument for this option
...
sendrecv.c: In function ‘main’:
sendrecv.c:125: warning: format ‘%u’ expects type ‘unsigned int’, but
argument 2 has type ‘size_t’

the other *_err_long warnings with MinGW64 might be because surprisingly
sizeog(long) is 4 instead of 8 ...

Gün.
