+
+ 1. The destructor supplied to __gthread_key_create is ignored for
+ generic x86-win32 ports. This will certainly cause memory leaks
+ due to unreclaimed eh contexts (sizeof (eh_context) is at least
+ 24 bytes for x86 currently).
+
+ This memory leak may be significant for long-running applications
+ that make heavy use of C++ EH.
+
+ However, Mingw runtime (version 0.3 or newer) provides a mechanism
+ to emulate pthreads key dtors; the runtime provides a special DLL,
+ linked in if -mthreads option is specified, that runs the dtors in
+ the reverse order of registration when each thread exits. If
+ -mthreads option is not given, a stub is linked in instead of the
+ DLL, which results in memory leak. Other x86-win32 ports can use
+ the same technique of course to avoid the leak.
+
+ 2. The error codes returned are non-POSIX like, and cast into ints.
+ This may cause incorrect error return due to truncation values on
+ hw where sizeof (DWORD) > sizeof (int).
+
+ 3. We are currently using a special mutex instead of the Critical
+ Sections, since Win9x does not support TryEnterCriticalSection
+ (while NT does).
+
+ The basic framework should work well enough. In the long term, GCC
+ needs to use Structured Exception Handling on Windows32. */

+ very argument sensitive: a space in the wrong place breaks everything.
+ So please forgive this mess. It works.
+
+ Parameters which can be passed to gcc, and their SCO equivalents:
+ GCC Parameter SCO Equivalent
+ -ansi -a ansi
+ -posix -a posix
+ -Xpg4 -a xpg4
+ -Xpg4plus -a xpg4plus
+ -Xods30 -a ods30
+
+ As with SCO, the default is XPG4 plus mode. SCO also allows you to
+ specify a C dialect with -Xt, -Xa, -Xc, -Xk and -Xm. These are passed
+ on to the assembler and linker in the same way that the SCO compiler
+ does.
+
+ SCO also allows you to compile, link and generate either ELF or COFF
+ binaries. With gcc, we now only support ELF mode.
+
+ GCC also requires that the user has installed OSS646, the Execution
+ Environment Update, or is running release 5.0.7 or later. This has
+ many fixes to the ELF link editor and assembler, and a considerably
+ improved libc and RTLD.
+
+ In terms of tool usage, we want to use the standard link editor always,
+ and either the GNU assembler or the native assembler. With OSS646 the
+ native assembler has grown up quite a bit. Some of the specs below
+ assume that /usr/gnu is the prefix for the GNU tools, because thats
+ where the SCO provided ones go. This is especially important for
+ include and library search path ordering. We want to look in /usr/gnu
+ first because frequently people are linking against -lintl, and they
+ MEAN to link with gettext. What they get is the SCO intl library. Its
+ a REAL pity that GNU gettext chose that name; perhaps in a future
+ version they can be persuaded to change it to -lgnuintl and have a
+ link so that -lintl will work for other systems. The same goes for
+ header files. We want /usr/gnu/include searched for before the system
+ header files. Hence the -isystem /usr/gnu/include in the CPP_SPEC.
+ We get /usr/gnu/lib first by virtue of the MD_STARTFILE_PREFIX below.
