* summary: hsc2hs wrapper script ignores default flags => hsc2hs wrapper
script throws away $HSC2HS_EXTRA's value when
specified C compiler to use
Comment:
The default flags means $HSC2HS_EXTRA in the script. On OS X, ghc can only
build 32 bit binary, so hsc2hs should be operated to build 32bit binary.
For example, when I install a package which will build some *.hsc files
(e.g. network) with Cabal, I expect hsc2hs will be passed the flags to
build 32bit binaries. But Cabal passes --cc flags to hsc2hs, so
$HSC2HS_EXTRA's value becomes empty, hsc2hs goes wrong. Because gcc on OS
X will build 64bit binary as default.
And I think this is the problem about the wrapper script. My wrapper
script will ignore $HSC2HS_EXTRA only when specified C compiler to use is
not gcc.
