Re: autoconf

When I add those lines to configure.ac
I added them near the end immediatly after this line
"AC_MSG_RESULT(${enable_experimental-no})"

the "./configure" portion of building works, but it dies on make with the 
following error

"
checking for lirc_init in -llirc_client... yes
./configure: line 28725: syntax error near unexpected token `newline'
./configure: line 28725: `  yes:no:'
make: *** [config.status] Error 2
"

This particular line is the last line generated by ./configure command, 
and appears in different parts of the file depending on where the autoconf 
steps have been added.  I Have added in the part of the configure file 
that is causing the error.

line number 28725 reads "  ac_header_preproc=no" for reference.

Any advice on how to fix this is much appreciated.
The problem is especially annoying, because once the configure file has 
become corrupted, it can't be run again in an effort to fix itself. The 
"bad" parts of the file are being created by the lines in the origional 
message (which I have left at the bottom of the letter).  Once they become 
a part of the configure file it's ruined, and I have to go scrounge up a 
new copy.

Dave
