/* Original code from Mozilla */

|
|
|
// On x86 linux, the current builds of some popular plugins (notably
|
|
// flashplayer and real) expect a few builtin symbols from libgcc
|
|
// which were available in some older versions of gcc. However,
|
|
// they're _NOT_ available in newer versions of gcc (eg 3.1), so if we
|
|
// want those plugin to work with a gcc-3.1 built binary, we need to
|
|
// provide these symbols. MOZ_ENABLE_OLD_ABI_COMPAT_WRAPPERS defaults
|
|
// to true on x86 linux, and false everywhere else.
|
|
//
|
|
// The fact that the new and free operators are mismatched mirrors the
|
|
// way the original functions in egcs 1.1.2 worked.
