Modify the tc-getCPP and tc-getBUILD_CPP functions to use "$(tc-getCC) |
2 |
-E" (i.e. the C compiler's preprocessing call) instead of falling back |
3 |
to 'cpp'. This ensures that in environment with CC (and CXX) overriden |
4 |
the correct compiler is used rather than the one selected by gcc-config, |
5 |
which in turn fixes gcc version queries. |
6 |
|
7 |
The alternative would be to always override CPP along with CC & CXX. |
8 |
However, that is uncommon and is known to break some packages. |
