Standard practice is to resize the initial allocation.  You haven't
suddenly discovered some better way of doing things, you're just repeating
old mistakes.

No.  It's something you need to either calculate manually or write a
new program to calculate for you.  You might as well add the small bit
of code to your EXE and do it properly.  Then it becomes no different
than how your source code is converted to an EXE, because it is part of
your source code that's converted to an EXE.

You're assuming that the minalloc value that the linker comes up with is
the correct value.  Resizing the initial allocation is also how you ensure
that the actual minimal amount of memory your program needs is available.
