687791 "Problems with VC6 makefiles (NDEBUG, /MTd)".

Raph or Ray,

http://bugs.ghostscript.com/show_bug.cgi?id=687791

Replace use of the assert macro with the GS_ASSERT macro that 
calls assert in debug code, but not in release code.
Partial fix for bug #687791 "Problems with VC6 makefiles (NDEBUG, 
/MTd)".

DETAILS:
The use of assert (even in release code) is acceptable in cases 
where the assertion failure is clearly a logic error in the code, 
rather than an exception case from, say, invalid input date. 
An assert is especially useful when catching the assertion early 
prevents a crash or more mysterious error condition later.

The system assert macro is troublesome in release code.
On some systems (e.g. when GS is running from a Windows service) 
it can result in an invisible dialog box which blocks the program.

Ghostscript code should use the GS_ASSERT macro rather than
the system assert macro.
In debug code, GS_ASSERT uses the system assert macro.
In release code, GS_ASSERT writes a message to stderr and continues.
Note that GS_ASSERT does generate code in release builds,
and will slow down execution.

/* Definitions for using assert in ghostscript code */

/* 
 * The use of assert (even in release code) is acceptable in cases 
 * where the assertion failure is clearly a logic error in the code, 
 * rather than an exception case from, say, invalid input date. 
 * An assert is especially useful when catching the assertion early 
 * prevents a crash or more mysterious error condition later.
 *
 * The system assert macro is troublesome in release code.
 * On some systems (e.g. when GS is running from a Windows service) 
 * it can result in an invisible dialog box which blocks the program.
 *
 * Ghostscript code should use the GS_ASSERT macro rather than
 * the system assert macro.
 * In debug code, GS_ASSERT uses the system assert macro.
 * In release code, GS_ASSERT writes a message to stderr and continues.
 * Note that GS_ASSERT does generate code in release builds,
 * and will slow down execution.
