5. Build and portability issues
5.1 OS400 port requires deprecated IBM library
5.2 curl-config --libs contains private details
+ 5.3 LDFLAGS passed too late making libs linked incorrectly
5.6 Cygwin: make install installs curl-config.1 twice
5.11 configure --with-gssapi with Heimdal is ignored on macOS
5.12 flaky CI builds
that might be needed only for building libcurl. Further, curl-config --cflags
suffers from the same effects with CFLAGS/CPPFLAGS.
+5.3 LDFLAGS passed too late making libs linked incorrectly
+
+ Compiling latest curl on HP-UX and linking against a custom OpenSSL (which is
+ on the default loader/linker path), fails because the generated Makefile has
+ LDFLAGS passed on after LIBS.
