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.
