Enhancements

The LARCH_PATH and LCLIMPORTDIR environment variables can now be overridden using the command line flags -larchpath and -lclimportdir.

Added special handling for "%m" in syslog format string (it does not consume an argument) (tests2.4/syslog.c)

Better hints for type errors (in presence of pointers) added +charunsignedchar flag

Added support for gcc extentsion __alignof__ (tests2.4/alignof.c)

Support LL and ULL constant designators and long long and unsigned long long types (in C99) (suggested by Martin Smoot)

Support wildcards in Win32 command lines (by linking with setargv.obj).

Bug Fixes

Fixed case/default parsing by making them markers instead of statements (switch (p) { case 2: } produced a parse error). (See tests2.4/emptycase.c.)

Switch Body Structure Fixed symbol table structure to support unstructured cases:

    switch(a) {
    case 1:   
      while (c>3) {
	case 3: ++c;
      }
    }     

In the hope that this won't encourage more code like this! (See tests2.4/duffs.c, bug1.c, bug2.c, bug3.c.)

Fixed label parsing to handle labels not followed by statements (Reported by N. Komazaki) (See tests2.4/komazi.c.)

Fixed pre-processor bug handling command line definitions with parameters (e.g., lclint '-D__P(x)=x') (tests2.4/cpptest.c)

Fixed handling of spaces in command line definitions (-D X=3) (reported by Daniel Barker) (tests2.4/command line)

Incorporated pre-processor fix sent in by N. Komazaki

Fixed handling of "#" (empty) in cpp (reported by Ulrich Ottersbach) (tests2.4/ulrich.c)

Added warning for comment open ("/*") inside comment (tests2.4/innercomment.c)

Fixed handling of direct pathnames in lcl files (reported by Dana Harrington) (tests2.4/subdir/main.lcl)

Fixed handling of function pointer declarations like, void (**(sig_func))(void);. (reported by Buck Hodges) (tests2.4/enumtest.c)

Fixed handling of static function declarations inside method scopes (tests2.4/nothing.c)

Fixed handling of %n printf format. It should be /*@out@*/ int * (tests2.4/print.c)

Added checking for enum members types (using initializers)

Fixed parsing of undefined system-like identifiers in enum member lists (reported by Steve Fink) (tests2.4/fink.c)

Fixed handling of gcc extension __extension__ (should not be treated as a token) (tests2.4/driverstub.c)

Hexidecimal constants (e.g., 0xFF) are typed as unsigned, but decimal constants are signed.

Fixed parsing of offsetof expressions, like:

typedef struct { union { int i; } u; } S;
int main() { return (int)offsetof(S, u.i); }

An internal error is raised for casts in bitfield widths:

typedef unsigned S;
typedef struct {
  unsigned u : ((S)4);
} T;
