+dnl apr_hints.m4: APR's autoconf macros for platform-specific hints
+dnl
+dnl We preload various configure settings depending
+dnl on previously obtained platform knowledge.
+dnl We allow all settings to be overridden from
+dnl the command-line.
+dnl
+dnl We maintain the "format" that we've used
+dnl under 1.3.x, so we don't exactly follow
+dnl what is "recommended" by autoconf.
+
+dnl
+dnl APR_PRELOAD
+dnl
+dnl Preload various ENV/makefile params such as CC, CFLAGS, etc
+dnl based on outside knowledge
+dnl
+dnl Generally, we force the setting of CC, and add flags
+dnl to CFLAGS, CPPFLAGS, LIBS and LDFLAGS.
