Hiho,

FYI:

[stephan@host:~/cvs/fossil/sqlite4]$ time (make TCC=tcc BCC=tcc &>/dev/null)

real 0m0.985s
user 0m0.532s
sys 0m0.244s

gcc takes about 8 seconds on my box (Linux x64).

the tests have more errors with tcc (either 8 or 11 of 34621 tests,
depending on the temperature and time of day, whereas gcc currently has 5).
Runtime of the tests with tcc is roughly 20% longer (40 vs 48 seconds on my
machine).

It also, since yesterday, builds in C89 mode with two minor caveats
regarding 'long long' and vsnprintf(). If i can find portable workarounds
for those i'll fix that. (sqlite4_vsnprintf() behaves differently and
breaks the vsnprintf()-using LSM code.)

Happy hacking!
