[Tinycc-devel] TCC preprocessor bug

[Szabó Péter]

Dear Developers,

The attached source code (derived from an IOCCC entry) compiles fine in 
GCC 2.95 and GCC 3.0, but fails with TCC:

        $ gcc -ansi -W -Wall ~/pts/fanf1.c
        /home/guests/pts/pts/fanf1.c: In function `b':
        /home/guests/pts/pts/fanf1.c:640: warning: unused parameter `c'
        /home/guests/pts/pts/fanf1.c: In function `d':
        /home/guests/pts/pts/fanf1.c:640: warning: unused parameter `c'
        /home/guests/pts/pts/fanf1.c: At top level:
        /home/guests/pts/pts/fanf1.c:644: warning: `main' takes only zero or 
two arguments
        /home/guests/pts/pts/fanf1.c: In function `main':
        /home/guests/pts/pts/fanf1.c:644: warning: unused parameter `c'
        $ gcc -v
        Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
        gcc version 2.95.4 20011002 (Debian prerelease)
        $ tcc -v
        tcc version 0.9.22
        $ tcc ~/pts/fanf1.c
        /home/guests/pts/pts/fanf1.c:636: warning: assignment makes pointer 
from integer without a cast
        /home/guests/pts/pts/fanf1.c:680: field not found

I think the bug is in the TCC preprocessor, because TCC can compile the 
program after running `gcc -E' on it.

Best wishes,

Péter
