Let me try:
pavel@n900:/my/bluez$ autoconf
configure.ac:4: error: possibly undefined macro: AM_INIT_AUTOMAKE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:11: error: possibly undefined macro: AM_MAINTAINER_MODE
configure.ac:24: error: possibly undefined macro: AM_PROG_CC_C_O
configure.ac:25: error: possibly undefined macro: AC_PROG_CC_PIE
configure.ac:32: error: possibly undefined macro: AC_DISABLE_STATIC
configure.ac:33: error: possibly undefined macro: AC_PROG_LIBTOOL
configure.ac:41: error: possibly undefined macro: AM_CONDITIONAL
pavel@n900:/my/bluez$ ./configure
./configure: line 2189: syntax error near unexpected token `foreign'
./configure: line 2189: `AM_INIT_AUTOMAKE(foreign subdir-objects color-tests silent-rules'
pavel@n900:/my/bluez$
automake; autoconf results in less warnings out of autoconf.
In the end I just deleted the offending line.
But then it ends here:
./configure: line 4043: AM_PROG_CC_C_O: command not found
./configure: line 4044: AC_PROG_CC_PIE: command not found
configure: error: cannot find install-sh, install.sh, or shtool in "."
"./.." "./../.."

That was my fault, not kernel fault. I just relied on scrollback
buffer, and it was not big enough.

Aha. Ok, I guess I can test out the patches... if I manage to compile
it. Adding a hint how to compile from git (-> configure not present)
would be nice.

Actually, I guess I can just make it build-in. But I'm not sure how it
is supposed to help: I'd expect undefined symbols on broken
dependency, not silent failure.
Thanks,
Pavel
