No,and yes,now :)
It compiles and runs as expected,another send mail example also
works great.
To summary,to write a reminder to myself,and a very simple
reference to anybody who may encounter this issue and try to fix
it---
Environment:Windows 10 64bit,DMD 2.106,VS Community 2019.
1.Modify curl.h as described above;
2.D wrapper file curl_d.c to curl.h:
#include
//in my system include string.h is required,
//otherwise dmd complains strlen and memcpy is not defined
#include
//in my system #include dosn't work,although
//curl ,curl/include,curl/lib is already in system enviroment
path
//provide curl.h path relative to this wrapper
#include "include/curl/curl.h"
3.main.c source file:
#include
#include "curl_d.c"
int main(void){ return 0;}
4.compile with :dmd -m64 main.c curl_d.c curl.lib
That is it.
5.main.d source file:
import core.stdc.stdio;
import curl_d;
//otherwise 2 printf candidates conflict in my system
alias printf=core.stdc.stdio.printf;.
int main(){ return 0;}
6.compile with dmd:dmd -m64 main.d curl_d.c curl.lib

They are MSVC compiler intrinsics.
(https://issues.dlang.org/show_bug.cgi?id=23894)
Surprisingly I got it working by just replacing some includes
with definitions in "curl/curl.h".
Change:
```c
#if defined(_WIN32) && !defined(_WIN32_WCE) &&
!defined(__CYGWIN__)
#if !(defined(_WINSOCKAPI_) || defined(_WINSOCK_H) || \
defined(__LWIP_OPT_H__) || defined(LWIP_HDR_OPT_H))
/* The check above prevents the winsock2 inclusion if winsock.h
already was
included, since they can't co-exist without problems */
#include
#include
#endif
#endif
```
to:
```c
#if defined(_WIN32) && !defined(_WIN32_WCE) &&
!defined(__CYGWIN__)
#if !(defined(_WINSOCKAPI_) || defined(_WINSOCK_H) || \
defined(__LWIP_OPT_H__) || defined(LWIP_HDR_OPT_H))
typedef unsigned short u_short;
typedef unsigned intu_int;
typedef struct sockaddr {
#if (_WIN32_WINNT < 0x0600)
u_short sa_family;
#else
ADDRESS_FAMILY sa_family; // Address family.
#endif //(_WIN32_WINNT < 0x0600)
char sa_data[14]; // Up to 14 bytes of
direct address.
} SOCKADDR;
#if(_WIN32_WINNT >= 0x0501)
typedef unsigned __int64 u_int64;
#endif //(_WIN32_WINNT >= 0x0501)
#if defined(_WIN64)
typedef unsigned __int64 SOCKET;
#else
typedef unsigned int SOCKET;
#endif
#ifndef FD_SETSIZE
#define FD_SETSIZE 64
#endif /* FD_SETSIZE */
typedef struct fd_set {
u_int fd_count; /* how many are SET? */
SOCKET fd_array[FD_SETSIZE]; /* an array of SOCKETs */
} fd_set;
#endif
#endif
```
At least this example program
(https://curl.se/libcurl/c/getinfo.html) works fine.
