Hi, jianxin.
Thx very much for your suggestion.
(1) SRCPOS is defined to mUINT64.
In fact, mUINT32 is big enough for line number even if 16bit machine.
And in gcc-front-end, decl_line is declared as INT.
(2) IN STMT_NODE, linenum is defined as mUINT64, not a macro
If use a macro to define line in ST,
The print format will take a little bit more work
