--- Begin Message ---Hello, Thanks to Ralf Wildenhues hint I discovered there is an upstream bug. FYI: if you look carefully into AC_TRY_RUN call you will notice that the last right square bracket is superfluous one. Replacing the last line with: }], initstate_r_works=yes,,) makes everything works correctly. The other qestion is if autoconf should be able to detect such a syntax error in configure.ac code and report it to the operator. I left the answer to the autoconf maintainer. Regards Artur -- Documentation is like sex: When it is good, it is very, very, good. And when it is bad, it is better than nothing. /Dick Brandon/
