[sv-cc] Old-style function prototypes in svdpi.h

The following was posted in the Verification Guild forum at http://verificationguild.com/modules.php?name=Forums&file=viewtopic&t=4366:

The svdpi.h file specified by IEEE 1800 gets compilation warnings when compiled with gcc 3.4.6 using the -Wstrict-prototypes flag.

For instance this function prototype:
XXTERN const char* svDpiVersion();

My 1988 K&R book says of the above syntax: "This special meaning of the empty argument list is intended to permit older C programs to compile with new compilers. But it's a bad idea to use it with new programs. If the function takes arguments, declare them; if it takes no arguments, use void." Certainly, svdpi.h is one of these post-1988 "new programs."

I believe that svdpi.h should change the four offending lines to the modern syntax:
XXTERN const char* svDpiVersion(void);
XXTERN svScope svGetScope(void);
XXTERN int svIsDisabledState(void);
XXTERN void svAckDisabledState(void);

The same may apply to some of the other .h files specified in the standard, but I haven't checked.
