Thanks Rob for chipping in. My suggestion was probably a little
too speculative, sorry, it was not a helpful suggestion anyway.
Sorry to have distracted you, perhaps you should just delete
off-on-a-wild-blue-yonder stuff like this next time, unless it is
a valid bug, etc. :-)

I tried that on Ubuntu 6.10. Just "./tcc" alone core dumps; if
he's asking about why "./tcc qwert" failed, I'd question whether
he has done any homework himself. So if Mike wants to play with
non-standard link options, he'd better be prepared to conduct some
investigation of his own. Perhaps he needs to write a test case
for *gcc* that works with the -nostdlib thingy and exercises the
bunch of symbols tcc needs, before attempting the same trick on
the whole kaboodle.

My first posting was mainly out of concern; enthusiasts should not
be routinely asking for the very limited resources of tcc
developers or the list to chase down these things -- it is not a
real good use of their time. On the Mingw list, there was two
cases in two weeks where somebody treated the list like tech
support, and in a demanding and somewhat belligerent manner. Us
old-timers gawk mutely and wonder in awe at such audacious
jaw-dropping behaviour. :-)
