Description

I downloaded 1.6.7 and tried building. It failed at the native compilation step against gcc 4.7

Removing the flag -mimpure-text from the cext/src/Makefile seemed to work!

g++: error: unrecognized command line option ‘-mimpure-text’

This occurs from the build-jruby-cext-native ant task or by running make directly from command line in the cext/src directory.

Indeed, http://gcc.gnu.org/onlinedocs/gcc/Option-Summary.html indicates that -mimpure-text is a Solaris-only flag.

The funny thing is that it's been there since January 2010.

Perhaps older GCC was more lenient?

The flag does not exist on master. I pushed a fix to the 1.6 branch (13bccdd), but I don't know if we are going to have another 1.6.x release.
