"cc" is the standard C compiler name defined in POSIX, so ideally any |
| 20 |
gcc-agnostic programs should use "cc" instead of "gcc". Practically, |
| 21 |
build tools like GNU Make and CMake would be affected as they use "cc" |
| 22 |
implicitly. |
| 23 |
|
| 24 |
OTOH, POSIX doesn't require the presence of C++ compiler on a |
| 25 |
conformant system; "c++' is just a de facto standard. |
