This +commit removes the hard-coded list of C++ compilers, and the manual +computation of REQ_CXXFLAGS based on the name of the compiler. + +This serves another purpose: the qd-config program is capable of +outputting an appropriate "-I" flag to allow consumers to use libqd +when it is installed in a nonstandard location. At the moment, however, +that "-I" flag is accompanied by whatever other REQ_CXXFLAGS were +computed -- and many of those flags are invalid in the other context. +By eliminating REQ_CXXFLAGS, we solve that problem too. +--- + configure.ac | 43 +------------------------------------------ + 1 file changed, 1 insertion(+), 42 deletions(-) + +diff --git a/configure.ac b/configure.ac +index a657e8f..5ac7079 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -73,51 +73,10 @@ AC_MSG_RESULT($enable_warnings) + + # Checks for programs. + AC_LANG(C++) +- +-# Set up compiler search list.
