AM_CXXFLAGS instead of CXXFLAGS

[Mateusz Loskot]

Hi,

I'd like to request for small change.
As I see, in almost all Makefile.am files CXXFLAGS variables are
set manually.

When user want's to customize these flags, automake throws:

Src/UnitTest/Makefile.am:196: `CXXFLAGS' is a user variable, you should
not override it;
Src/UnitTest/Makefile.am:196: use `AM_CXXFLAGS' instead.


Automake book says:
http://sources.redhat.com/autobook/autobook/autobook_40.html

"These variables are considered user variables. Setting
them in `Makefile.am' is unsafe, because the user will
expect to be able to override them at will."

Following FAQ includes short explanation of it too:
http://www.kdevelop.org/index.html?filename=3.0/faq.html&set_lang=en#18

Do you mind to change CXXFLAGS variable to AM_CXXFLAGS macro
(supported by automake >= 1.4) ?

Thanks in advance.
