Lassi Kortela 9d4bf19367 Fix regression in ios_printf implementation 
There was some problem with the way the varargs are handled. We had to
need to make (at least one) copy of them with va_copy(). The code is
brittle and I don't understand it, so just rip it all out and replace
with a fixed-size static buffer. It's a hack but we'll soon get rid of
printf completely so this will get us through the day until then.

 2019-08-21 22:17:06 +03:00
Lassi Kortela b2027fe023 Split setenv/unsetenv by platform 
Windows apparently doesn't have unsetenv() at all, so use the WinAPI
native envar functions instead of the usual C ones.

Lassi Kortela 439eeb2b06 Use vsnprintf() instead of vasprintf() 
Windows doesn't reliably offer *asprintf() (sprintf functions that
automatically malloc as much memory as they need) so hand-roll the
equivalent on all platforms.

Lassi Kortela c76379e6f5 Brace try/except in main() for Watcom 2019-08-21 22:08:21 +03:00
Lassi Kortela 60ff06fb6d Reorganize error functions and includes 
These functions are complicated because they need to be marked
"noreturn" for the compiler. There are several fundamentally
incompatible ways of doing that. Since we have only a few "noreturn"
functions, let's just list all of those in one header file of which
there is a completely different version for each compiler.
