Some notes.  Configuration has changed to be a bit more consistent.
Below I change the configuration bits to new style.

Can I suggest that you name the configuration something different?

CONFIG_CHECK

means whatever, some for "check" variable in configure.

check_suite
test_suite

or anything else?
I think that "check" alone is not enough descriptive, but this is just a
nit pit.

We changed how to add libraries, you can remove this three lines.
See below where to add it.

Add both.

Remove this bit.

Rewrote this as:

if test "$check" != "no" ; then
  cat > $TMPC << EOF
#include <check.h>
int main(void) { suite_create("yeah"); return 0; }
EOF
  check_libs=`pkg-config --libs check`
  if compile_prog "" $check_libs ; then
    check=yes
    libs_tools="$check_libs $libs_tools"
  else
    if test "$check" = "yes" ; then
      echo "`check` not found and requested.  Please install"
      exit 1
    fi
    check=no
  fi
fi # test "$check"

Things that changed:
- two spaces indentation
- use compile_prog funciton
- Add check_libs here, not in Makefile

On my patches on staging, there is a function called feature_not_found

echo + exit in function will become:

feature_not_found "check"

just if your series got merged after my changes in staging.  nothing
else needs to be changed.

two last lines not needed, it becomes:

I guess you want to add something here to tools, otherwise, you are
doing nothing here :)

That is it.

Later, Juan.
