Ah, I see what you mean. Does the attached patch work for you?
Yes, it seems to fix configure.
There is, however, still the problem that library and include paths passed to configure via the environment (like LDFLAGS, CPPFLAGS) aren't recognized by cabal, so even if configure is successfull, cabal (or ghc-pkg configure, in my case) will fail.
In rules/build-package-data.mk there are two lines:
$1_$2_CONFIGURE_OPTS += --configure-option=CFLAGS="$$(filter-out -Werror,$$(SRC_CC_OPTS)) $$($1_CC_OPTS) $$($1_$2_CC_OPTS)" $1_$2_CONFIGURE_OPTS += --configure-option=LDFLAGS="$$(SRC_LD_OPTS) $$($1_LD_OPTS) $$($1_$2_LD_OPTS)"
If you add two more lines:
$1_$2_CONFIGURE_OPTS += --gcc-options="$$(filter-out -Werror,$$(SRC_CC_OPTS)) $$($1_CC_OPTS) $$($1_$2_CC_OPTS)" $1_$2_CONFIGURE_OPTS += --ld-options="$$(SRC_LD_OPTS) $$($1_LD_OPTS) $$($1_$2_LD_OPTS)"
then does that fix the problem?
The second added line doesn't work as expected. I explicitely have to set CFLAGS="-I/usr/local/include -L/usr/local/lib". It seems like cabal only uses --gcc-options when running gcc (and ignoring --ld-options). So for now, the addition of --gcc-options helps me to build ghc-head again. FYI, below is the output of ghc-cabal with an added -v3 when CFLAGS="-I/usr/local/include" (without -L/usr/local/lib).
