90dnl ChangeLog
91dnl 2006-02-13  * Check compiler return value instead of parsing the error stream,
92dnl               which detected warnings as false negatives (due to Jens Hannemann).
93dnl 2006-02-02  * Spelling of "Success".
94dnl             * Fixed unsave test for $bnv_qt_lib without quotes.
95dnl             * Put dnl in front of all comments.
96dnl             * Changed -l$bnv_qt_lib_dir into -L$bnv_qt_lib_dir (all due to Pavel Roskin).
97dnl 2006-01-19  * Support for 64bit architectures.
98dnl             * Updated documentation.
99dnl 2006-01-18: * Fix "cat: bnv_qt_test.c: No such file or directory" (due to Jens Hannemann).
100dnl             * Hide output of failing ls.
101dnl 2006-01-11: * Check in /Developer on Mac OS X; Check in $QTDIR (due to Brian Mingus).
