From the CW6 release notes:
* Support for GCC 'typeof':
char *cp;
int *ip;
long *lp;
__typeof__(*cp) c; // equivalent to "char c;"
__typeof__(*ip) i; // equivalent to "int i;"
__typeof__(*lp) l; // equivalent to "long l;"
Two new keywords:
'__typeof__' (always available)
'typeof' (only available when #pragma gcc_extensions is 'on')
