Re: [bug-recutils] Use pkg-config to find check

[Jose E. Marchesi]

Hi Michal.

    Hello.  The following patch, at branch check-pkg-config of
    git://git.mtjm.eu/mtjm-recutils.git, makes configure use pkg-config to
    find check instead of passing only -lcheck to the compiler.

Thanks for the patch.  I have just one comment, see below.
    
    diff --git a/configure.ac b/configure.ac

    -   CHECKLIBS=-lcheck
    -fi
    -AC_SUBST([CHECKLIBS])

If I remember properly some old versions of PKG_CHECK_MODULES will fail
to AC_SUBST CHECK_LIBS and CHECK_CFLAGS.  Would you mind to AC_SUBST
these variables explicitly, just in case?

Apart for that, please go ahead and push the change.
