AM_CFLAGS is passed both to the compiler (.c -> .o) and to the linker, so it
should only have flags that are appropriate for both steps. AM_CPPFLAGS is
passed only to the compiler, so flags that are only appropriate for that step
(-I and -D flags, for example), should be in _CPPFLAGS instead of _CFLAGS.
Every gnucash-2.2.3 Makefile.am that passes -I flags gets it wrong, placing
them in _CFLAGS. It's not a functional bug (the linker ignores -I flags), but a
ton of superfluous flags makes the build output pretty verbose and hard to
debug when things do go wrong.
To make matters more confusing as a developer, the FOO_CFLAGS variable set by
PKG_CHECK_MODULES(FOO) is actually for _CPPFLAGS in the Makefile.am
('pkg-config --cflags' returns the -I flags).
A related -I bug (one that *is* functionally broken) is that sometimes a local
(build dir) -I flag is passed after a global (installed dependent library) one.
If my system happens to have a header installed from some unrelated thing,
compiler will find *that* one instead of the expected one in the source
directory. Should always pass all local -I before any global ones.
Patch by andi5 plus one manual addition in src/gnome-utils/Makefile.am

This program, called as "prog.exe (arg)*", will search for
.\bin\prog.exe, ..\bin\prog.exe and so on. The first hit will be
spawned with the same parameters and its exit status will be the exit
status of this program.

In the long run it should be possible to build GnuCash on Windows from
the tarball within MSYS/MinGW.
