 2.  The % operator will generally not work correctly when either operand is negative.  It may produce an incorrect result, or in certain scenarios it may give a compile-time or run-time error.

 6.  The "#warning" preprocessor directive is now supported.  This behaves similarly to #error in that it causes any following tokens to be printed as a diagnostic message, but (unlike #error) it does not abort compilation.  (This is a non-standard feature, but compatible with other common compilers such as GCC and Clang.)
 
+7.  A new bit (bit 2, a value of 4) is introduced in #pragma ignore that permits spurious tokens to appear after the #endif directive.  If this bit is set, the tokens are treated as a comment, and have no effect on the program.  If this bit is clear, tokens after #endif are treated as an error.  (This feature was introduced in MPW IIgs ORCA/C and is compatible with it, but in this version the bit is unset by default, providing standard-compliant semantics.)

 Multi-Character Character Constants

 51.  An unlimited number of octal digits could be processed as part of an octal escape sequence in a character constant or string.  Octal escape sequences are now limited to a maximum of three octal digits, as required by the C standards.  (This partially reverts a change in ORCA/C 2.1.0, which should only have applied to hexadecimal escape sequences.)
 
+52. Fixed several bugs that could cause the loop invariant removal and common subexpression elimination optimizations to move code when it was invalid to do so.

+53. Added prototypes for internal functions called by macros in <stdio.h>, so they will not produce errors when certain #pragma lint options are used.
