I think I found an issue in the preprocessor of tcc.The following program:

TEST3((INIT(KO))) // ==> expect ok, get "error: macro 'KO' used

produces an error "error: macro 'KO' used with too many args"
Yikes! My eyes bleed, who writes such pre-processor abominations? ;-)
It's an interesting corner case that took some time to analyze. Basically
we must not look ahead too far for '(' when looking at a token that could
start a function-like macro invocation. But our implementation of "not
too far" was wrong. Fixed in mob d8fdd38 .
I wasn't able to reduce the test case any further.
Yeah. In above commit the testcase I added contains some lines showing
the problem already a bit earlier but not much.
Ciao,
Michael.
