And you got it. I actually started reviewing your patch. I never comment
code without looking at it - if you read the list you should know that by
now. I saw too many problems and decided to report them on the list instead
of going further. The fact that you fail to understand what I am speaking
about ... that I cannot explain.

Up to here you have shell code.

Here you have the macro AC_TRY_LINK and a simple C program passed to it as
an argument. The C program is written to a file and configure tries to build
it and this way it decideds whether the symbol SLsys_getkey() is available.

It is obvious that you are missing basic knowledge on configure magic. You
did some copy/paste and you expect that it will just work ?
