Thinking that any c compiler would do the job, I tried to use tcc with ikiwiki, as explicitely allowed by the Debian package dependencies.

I installed tcc and libc6-dev (for libcrt1). The wrapper compilation was OK, but the wrapper fails to run correctly and dies with

usage: ikiwiki [options] source dest
   ikiwiki --setup configfile

Everything works fine with gcc.

versions: Debian lenny + backports

Seems that tcc does not respect changing where environ points as a way to change the environment seen after exec

Given that the man page for clearenv suggests using environ=NULL if clearenv is not available, I would be lerry or using tcc to compile stuff, since that could easily lead to a security compromise of code that expects that to work. However, I have fixed ikiwiki to use clearenv. --Joey done
