# GOTCHA #1: FOX's configure.ac does `CXXFLAGS=""` unconditionally near the
# top and rebuilds it from scratch with its own hardcoded flag set - any
# CXXFLAGS/CFLAGS we export before running configure is silently discarded
# (confirmed by inspecting configure.ac: "CXXFLAGS=\"\"" then a chain of
# CXXFLAGS="${CXXFLAGS} ..." appends, never re-adding a user value).
# GOTCHA #2: within that rebuild, `XFTCFLAGS="-I/usr/include/freetype2"` is
# hardcoded (no pkg-config/freetype-config probe), so <ft2build.h> is never
# found under our $PREFIX=/usr/local.
# WORKAROUND: src/Makefile.am declares `CXXFLAGS = @CXXFLAGS@ @X_CFLAGS@`
# with no explicit CPPFLAGS reference, but automake's generated compile
# rule ALWAYS appends $(CPPFLAGS) regardless (it's a standard AC_SUBST'd
# variable automake wires in implicitly) - and configure.ac never touches
# CPPFLAGS at all. So route our include path through CPPFLAGS instead of
# CXXFLAGS/CFLAGS - it survives the configure.ac reset untouched.
# GOTCHA #3: FOX's include/xincs.h has a ready-made
# `#ifdef HAVE_SYS_FILIO_H #include <sys/filio.h> #endif` (for FIONREAD on
# Solaris/illumos) but configure.ac never actually probes for
# sys/filio.h/AC_DEFINE's HAVE_SYS_FILIO_H - it's a dead branch upstream.
# illumos DOES have <sys/filio.h> (confirmed present on Hammerhead) so just
# define the macro ourselves; FXGUISignal.cpp otherwise fails with
# "'FIONREAD' was not declared in this scope".
