#67729: lzma is broken now with Apple GCC: error: #pragma GCC diagnostic not
allowed inside functions

Port: lzma |

Comment (by kencu):
{{{
#if defined (__clang__) || defined(__GNUC__)
}}}
in insufficient as a test, as only newer gcc versions can support these
pragmas inside functions.
Something like this is better (from our cmake patch for Tiger):
{{{
#if defined(__GNUC__)
#define GCC_VERSION \
(__GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__)
#endif
#if defined(__clang__) || (defined(GCC_VERSION) && (GCC_VERSION >= 40500))
/* gcc diagnostic pragmas available */
# define GCC_DIAGNOSTIC_AVAILABLE
#endif
}}}
and then use
{{{
if defined(GCC_DIAGNOSTIC_AVAILABLE)
}}}
as the test.
