4 | <para>This package is known to behave badly when you have changed its default
|

5 | optimization flags (including the -march and -mcpu options). GCC is best
|
---|
6 | left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other
|

7 | such variables/settings that would change the default optimization that

11 | the C and C++ compiler. Other compilers are available within the gcc

12 | package. If you want to build all the other available compilers too,
|
---|
13 | leave out the --enable-languages=c,c++ option in the configure command.
