Problems running nsqlprep with Visual Studio 2005.

I have code which contains ESQL/C which is pre-processed by the Embedded SQL precompiler nsqlprep. This works fine when used with Visual Studio 6 but does not work when used with Visual Studio 2005.

As a simple test case I have a file called helloworld.sqc which contains the following text:

#include      <stdio.h>
int main()
{
      printf("hello world\n");
      return 0;
}

and I type

nsqlprep helloworld

from within a Visual Studio 2005 Command Prompt (Start -> All Programs -> Microsoft Visual Studio 2005 -> Visual Studio Tools), and I get

helloworld.sqc
Warning: helloworld.sqc, line 3235: syntax error.

(
Warning: helloworld.sqc, line 3262: syntax error.
(
Warning: helloworld.sqc, line 5: syntax error.
{


However, it runs and creates helloworld.c.

If I then type

cl helloworld.c

upon the helloworld.c which is produced by nsqlprep, I get

If we repeat this exercise where we have

INCLUDE=D:\Program Files\Microsoft Visual Studio\VC98\Include;
LIB=D:\Program Files\Microsoft Visual Studio\VC98\Lib

i.e. the Visual Studio 6 include files and libraries, then everything works OK.
