Log Message:
-----------
Update Scintilla to version 3.7.5 (#1503)
* Update Scintilla to version 3.7.5
This now requires a C++11-capable compiler.
Closes #1308.
* Test using newer dist on Travis
Since Scintilla needs C++11
* Add debugging code for when configure fails
* Workaround a pkg-config-corsswrapper bug on Ubuntu 14.04
See https://bugs.launchpad.net/ubuntu/+source/mingw-w64/+bug/1327242

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the C++11
+#   standard; if necessary, add switches to CXXFLAGS to enable support.
+#
+#   The first argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for an extended mode.
+#
+#   The second argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline C++11 support is required and that the macro
+#   should error out if no mode with that support is found.  If specified
+#   'optional', then configuration proceeds regardless, after defining
+#   HAVE_CXX11 if and only if a supporting mode is found.
