+Subject: [PATCH 10/12] configure.ac: don't manually search for compiler
+ names/flags.
+
+The AC_PROG_CXX macro is generally capable of finding the best C++
+compiler on the system these days, including the flags it needs.  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.
