Description changed by jdemeyer:
Old description:

> `compile foo.c`. Seeing the actual command line passed to `gcc` is very
> useful for debugging.
>
> 2. user-defined `CFLAGS` are not passed.
>
> 3. meataxe assumes that `char` is `signed char` but that is not
> guaranteed by the C standard. This causes breakage on powerpc64le. A
> work-around with GCC is `-fsigned-char` but it's better to fix the
> sources.
>
> 4. the test-suite has race conditions: testing with `MAKE="make -j48"`
> fails while `MAKE="make -j1"` works.
New description:
1. The actual command lines when compiling are hidden, all I see is
`compile foo.c`. Seeing the actual command line passed to `gcc` is very
useful for debugging.
2. user-defined `CFLAGS` are not passed.
3. meataxe assumes that `char` is `signed char` but that is not guaranteed
by the C standard. This causes breakage on powerpc64le. A work-around with
GCC is `-fsigned-char` but it's better to fix the C sources.
4. the test-suite has race conditions: testing with `MAKE="make -j48"`
fails while `MAKE="make -j1"` works.
