+If you experience crashes when visiting some sites, notable yahoo.com,
+using a different compiler will likely resolve these issues. Gcc-4.9.4
+is most likely the "best" compiler to use. Some users report that compiling
+with clang also resolves crashes. Both, clang and the default GCC Slackware
+ships with, however, are unsupported; but may work. If gcc-4.9.4 is installed
+and detected, the script will compile PaleMoon with it; however, if you pass
+the script the variable CC=clang and CXX=clang++ (for example) the script will
+atempt to compile PaleMoon using clang (replace clang and clang++ with
+whatever compiler is desired, and present in the system). If you desire to
+install and use gcc-4.9.4 (and need help), visit the wiki help link above.
