+dnl CF_GXX_WARNINGS version: 5 updated: 2005/08/13 14:54:38
+dnl ---------------
+dnl Check if the compiler supports useful warning options.
+dnl
+dnl Most of gcc's options apply to g++, except:
+dnl -Wbad-function-cast
+dnl -Wmissing-declarations
+dnl -Wnested-externs
+dnl
+dnl Omit a few (for now):
+dnl -Winline
+dnl
+dnl Parameter:
+dnl $1 is an optional list of g++ warning flags that a particular
+dnl application might want to use, e.g., "no-unused" for
+dnl -Wno-unused
+dnl Special:
+dnl If $with_ext_const is "yes", add a check for -Wwrite-strings
