Re: [Tinycc-devel] TCC very interesting error

I have found in google a solution for "undefined reference to `_chkstk'":

Current solution is to copy the CHKSTK.OBJ from MSVC6. I renamed it to chkstk.o so that CMake would let me link with it in MinGW. (url to that solution: http://eegeerg.blogspot.com/2008_01_01_archive.html#4158852069709002699)

But is it possible? Can it help in my problem? Or my case is somewhat different?

Adding this one more variable causes the local stack grow over 4096.  This
requires the usage of __chkstk on windows (because there, unlike on linux,
each new stack page needs to be touched explicitely to make sure it gets
physically mapped)

However there seems a problem with latest TCC having problems to assemble
its own __chkstk function.  In particular there are some 66 prefixes that should
not be there.  See below.

Mr. Frederic Feret, would you look into it ?
