Vms doesn't have fork.
It does have vfork/exec.
Fixincludes uses fork.
It appears fixincludes uses it in two ways:
1) can be replaced by vfork?
2) subject to configuration and easily avoided
Really -- I would suggest just use the more portable form in the case of #2 and
don't bother with any need to configure anything. It is to much slower to be
worth any hassle?
As well, libiberty's pex might be useful here -- to replace (v)fork/exe use.
I have an obvious two line patch but it is not yet tested -- fork -> vfork and
add a line to autoconf.
Also the two lines that check for x86-mingw and x86_64-mingw should just check
for mingw imho.
