[Tinycc-devel] Preprocessor bug prevents macro expansion

[Alexandre Becoulet]

Hi list,

Tcc fails to compile some code due to what seems like a preprocessor bug. Here 
is a test case:

#define CONCAT(a, b, c) a##b##c
#define FOO(a, b, c) CONCAT(a, b, c)
CONCAT(F, O, O)(X, Y, Z)

This should expand to XYZ (tryed with gcc, clang, intel and sun) but tcc 
preprocessor expands to CONCAT(X, Y, Z).

The expansion is performed properly when commenting out some nested macro 
check code in the preprocessor.
