Subject: Use --cppflags-searchpath to get ICU includes
X-Git-Url: http://git.indexdata.com/?p=m4-moved-to-github.git;a=commitdiff_plain;h=e36f2d8ce81592ee2ecf29050da9c758e53adc05

Use --cppflags-searchpath to get ICU includes

Use icu-config --cppflags-searchpath instead of icu-config --cppflags.
Problem is that it --cpflags does not always contain include path.
Seen with ICU 4.6.1 on Solaris 5.10, GCC 3.4.3.
