Sun CC has __typeof__ since 5.9: http://developers.sun.com/sunstudio/support/CCcompare.html
I'm not sure which one of your flags make CC use "typeof" instead of __typeof__ but I think we should use __typeof__ on Sun as indicated by the link above and as currently and correctly detected by Boost.Typeof (before Boost.Config changes __typeof__ to typeof).
-Qoption ccfe -features=gcc. To build Boost with SunProCC you're going to have to pass several -Qoption ccfe -features=<X> to the compiler anyway. Might as well bite the bullet and pass them. :-) Otherwise, no dice, it won't build. Also, the document page you are referring to shows an inconsistency between the typeof operator implementations in SunProC vs. SunProCC: http://developers.sun.com/solaris/articles/c_type.html SunProC allows typeof (without underscores) by default, without any special flags: [steleman@darthvader][~/tmp][04/04/2012 23:04:00][1122]>> /opt/oracle/solarisstudio12.3/bin/cc -m32 -g -xO3 typeof.c -o typeofC [steleman@darthvader][~/tmp][04/04/2012 23:04:09][1123]>> ./typeofC ./typeofC [steleman@darthvader][~/tmp][04/04/2012 23:04:13][1124]>> echo $status 0 [steleman@darthvader][~/tmp][04/04/2012 23:04:17][1125]>> cat ./typeof.c #include <stdio.h> int main(int argc, char* argv[]) { typeof (typeof (char*)[4]) y0; typeof (int*) y1[4]; char* y2[4]; int* y3[4]; (void) fprintf(stderr, "%s\n", argv[0]); return 0; } But, neither typeof nor __typeof__ are part of any Standard anyway. --Stefan -- Stefan Teleman KDE e.V. stefan.teleman@gmail.com
