SUMMARY
=======

When compiling a program with the Microsoft C/C++ compiler, the following error
may be generated if an integer constant is recognized syntactically as being in
an illegal location:

   error C2059: syntax error: 'int constant'

Microsoft C/C++ 7.0 and Visual C++ may generate the following:

   C2143: syntax error: missing ';' before 'constant'

   -or-

   C2143: syntax error: missing ';' before 'int constant'

Depending on the code, this error may result from a failure to include a line
continuation character in a multi-line #define or macro definition statement, or
from placing an integer constant on a line by itself.

MORE INFORMATION
================

The sample code below demonstrates how this particular error might be generated.
The #define statement spans two lines, but the line continuation character (a
backslash) was inadvertently omitted from the end of the first line. This causes
the compiler to "see" the integer constants as being on a line by themselves
without any contextual meaning, and thus the C2059 error is generated.

Sample Code
-----------

   /* Compile options needed: none
   */ 

   #define coordinates {
         16,16  }

   void main(void)
   {
   }
