__alignof__ seems like it might be of some help: http://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/Alignment.html#Alignment But unfortunately it doesn't tell me what the _strictest_ alignment rule is, which is what I need to know to write a generic memory allocator.
I did a little bit of Googling and it seems that there is no defined standard here.
You might apply __alignof__ to a variable with "__attribute__ ((aligned)" in order to find out "the largest alignment which is ever used for any data type on the target machine you are compiling for":
