[Tinycc-devel] [PATCH] Preprocessor: ignore everything after #error or #warning

[Marc Andre Tanner]

Hi,

There seems to be a problem in the skiping of preprocessor directives,
tcc attempts to parse the string even after #error or #warning and
complains when it shouldn't.

cat > bug.c << EOF
#if 0
        #warning This doesn't work
#endif
EOF

tcc -c bug.c
bug3.c:4: missing terminating ' character

gcc -c bug.c

Marc
