I'm not a guru. But tcc behaviour cost me a day of the problem discovering

I don't think so. This alignment is for unusual sections, not for
.text .data and so.

I don't know about gcc defaults on different ARCH

May be. But problem exposed only on i386.

PS: another problem: 0x1234-123 parsed by tcc as float number by
default and there is no switch to dsiable this. And gcc-3.4.6 (4.1.2)
understand the above as expression 0x1234 - 123 by default.
