dnl THANKS! This code includes bug fixes and contributions made by:
dnl Tim McClarren,
dnl Dennis R. Weilert,
dnl Qingning Huo,
dnl Brian Mingus,
dnl Jens Hannemann,
dnl Pavel Roskin,
dnl Scott J. Bertin.
dnl ChangeLog
dnl 2006-03-12 * Hide output of ls and fix an m4 quoting problem (due to Scott J. Bertin).
dnl 2006-02-13 * Check compiler return value instead of parsing the error stream,
dnl which detected warnings as false negatives (due to Jens Hannemann).
dnl 2006-02-02 * Spelling of "Success".
dnl * Fixed unsave test for $bnv_qt_lib without quotes.
dnl * Put dnl in front of all comments.
dnl * Changed -l$bnv_qt_lib_dir into -L$bnv_qt_lib_dir (all due to Pavel Roskin).
dnl 2006-01-19 * Support for 64bit architectures.
dnl * Updated documentation.
dnl 2006-01-18: * Fix "cat: bnv_qt_test.c: No such file or directory" (due to Jens Hannemann).
dnl * Hide output of failing ls.
dnl 2006-01-11: * Check in /Developer on Mac OS X; Check in $QTDIR (due to Brian Mingus).
dnl Calls BNV_PATH_QT_DIRECT (contained in this file) as a subroutine.
