The testsuite makes some incorrect assumptions:

  - we need to not assume "a standard gcc", so replace the -Werror flag

    with -errwarn to turn on the warnings are expected to cause compilation

    to fail.

  - don't use the -pthread flag for compilation; as Studio doesn't have any

    clue what to do with it, and we don't need it on Solaris, anyway.

  - don't force the use of gcc when compiling a test shared object; get

    that passed in from the makefile.

  - don't assume that stdin/stdout/stderr are changeable:

        https://bitbucket.org/cffi/cffi/issue/145/solaris-stdout-and-stderr-not-in-libc-not

    fixed in

        https://bitbucket.org/cffi/cffi/commits/237031079adc

  - don't assume that enums can be unsigned or are the same size as long:

    https://bitbucket.org/cffi/cffi/issue/143/test_enum_size-makes-invalid-assumptions

Also fix a problem with some assignments to void*:

    https://bitbucket.org/cffi/cffi/issue/146/incorrect-type-for-c_callback-variable

fixed in
