<body class='hmmessage'>> These are OS-dependent! They should not be in BasicCtypes.<BR><BR>
1) There is no Utypes on Windows.<BR>
These are very basic types that belong at a very low level.<BR>
In C++ for example, size_t is provided "automatically" by the compiler, no header is needed.<BR>
<BR>
2) Are they really OS dependent? What OS makes my definitions wrong?<BR>
On what 32 bit architecture is size_t not an unsigned 32 bit integer and ptrdiff_t not a signed 32 bit integer?<BR>
Ditto for 64 bit.<BR>
These should always be the same size as a pointer and with the proper signedness.<BR>
Even if some of the *.i3 files make size_t = int, is that really correct?<BR>
And, I assume int vs. long issue is not an issue here.<BR>
Though they may be different types in C and C++, they need not be in Modula-3 (when they are the same size, of course)<BR>
