See what's happening?  Read up about m4 quoting:
  info Autoconf "M4 Quotation"

Short story: [ ] are quotation characters within configure.ac files.
That's one reason why many m4 macros use "test" instead for readability.

Nope, it doesn't.  The stuff you are seeing is the expansion of the two
AC_CHECK_LIB macros you use.  The end of the case statement will be
after them.  Side note: if they were indeed gone, your shell would've
screamed "syntax error" or something similar and bailed out.

I don't think so.

Look at config.log for what else might've gone wrong, it most likely is
independent of the configure.ac snippet you posted.  Post parts of
config.log if you can't figure it out.

Cheers,
