This appendix describes the differences between versions 6.0 and 7.0 of Microsoft C, including additions, deletions, and changes. Some of the changes are required by the American National Standards Institute (ANSI) standard for the C programming language. Other changes improve or augment the existing capabilities of the compiler.
Many of the changes will have no effect on code that was written and compiled with previous versions of Microsoft C. In some cases, however, you may have to modify or correct existing code before compiling with version 7.0.
