RE: errors building guile 1.8.6 for Interix 3.5, with some small patches

[Jay]

Here is a very strange but successul fix for the hang. Now guile 1.8.6 builds all the way through for me.

This is very typical of configure problems now in my experience.
configure compiles one way, checks for linking.
Compilation then does something different and fails.
I have seen this many times now in various projects.

Hm. reading stime.c makes me think defining _REENTRANT would be better,
since it probably only gives where _POSIX can take away?
So, this also worked:

Surely:
#if !defined(_REENTRANT) && defined(__INTERIX)
would also work if you want to narrow it down (but stime.c doesn't).

I don't see these prototyped anywhere.
I don't know if this patch is acceptable, since it doesn't adapt in the future if Interix improves.
I also think there is confusion here between HAVE_SETEUID and HAVE_SETEGID.
It appears gnulib could help with unsetenv.

and it hangs.
I'll try to look into that later but might just configure -disable-doc and move on, leaving it hanging for anyone else. :(
