-Caveat 1: even with @code{--disable-all-pkgs}, dependencies will be

-Caveat 2: unless @code{CC} and @code{CXX} and @code{OBJCXX} are
-explicitly specified, each package will configure its own compiler(s).
-In practice, this results in a conflict in only one instance: the ICU
-(@file{libs/icu}) library will prefer @code{clang} and @code{clang++}
-over all others if they are installed, whereas everything else prefers
- at code{gcc} and @code{g++}.  Usually the results will be interoperable,
-but it can cause extra confusion and problems when debugging a program
-that uses ICU.
+By default, the @code{gcc} compilers will be used if present;
+otherwise, individual packages may use something different.  You can
+explicitly specify the compilers to be used with the environment
+variables @code{CC}, @code{CXX}, and @code{OBJCXX}.
