In bug 79936 - ICE with -Walloc-size-larger-than=32767 the reporter encountered an ICE on x86_64-apple-darwin10.8.0 caused by GCC source file that implements the warning accessing a global tree without having included the file in GTFILES make variable. (Thanks again to David Malcolm who helped me root cause this bug.)
The attached patch fixes this by adding calls.c to the variable and by including the requisite generated header, gt-calls.h, at the end of the source. Martin
