3. Add the redundant #ifdefs to all compilation-dependent C files to
make sure that they are ignored when the libraries they require are
missing. For example, openssl.c should be wrapped in #ifdef
HAVE_OPENSSL.
So should http-ntlm.c. But using GNU make it's pretty easy to avoid;
I use my homebrew makefile with things like:
USE_OPENSSL = 1
USE_GNUTLS = 1
...
ifeq ($(USE_OPENSSL),1)
CFLAGS += -DHAVE_OPENSSL -I$(OPENSSL_ROOT)/outinc
SOURCE = openssl.c http-ntlm.c
endif
....
SOURCE += cmpt.c connect.c ...
If you adopt this style, I urge you to reconsider the "#undef HAVE_OPENSSL" in
config.h.
Instructing users (via windows/README) to change USE_OPENSSL in windows/Makefile
is so much easier/cleaner.
5. Create windows/Makefile-$compiler for each $compiler we support,
which contains the necessary CFLAGS, LDFLAGS, etc. configure.bat
--$compiler would copy both windows/Makefile and
windows/Makefile-$compiler to src.
I think a single windows/makefile is enough. Instruct make to put objects for each
target into separate sub-dirs. Along the lines of:
MSVC_OBJECTS = $(addprefix MSVC_obj/, $(SOURCE))
MINGW_OBJECTS = $(addprefix MingW_obj/, $(SOURCE))
MSVC_obj/%.obj: %.c
cl -c $(MSVC_CFLAGS) -Fo$@ $<
MingW_obj/%.obj: %.c
gcc -c $(MINGW_CFLAGS) -o $@ $<

And issuing "make -f ../windowsMakefile msvc" would AFAICS remove the
need for a configure.bat file (add the rules for ./doc to the same
windows/Makefile).
