poll() check and bootstrapping

[Tomáš Čech]

Hello,

I'm trying to clean the openSUSE spec file (recipe for build or RPM
package) and I found some workarounds which I believe should get fixed
in upstream instead.

1] I found that we're running whole build in screen to correctly pass poll() 
test
  ("checking if poll really works")

I asked our ncurses maintainer to patch the configure instead
involving terminal emulator in the build but I believe that it is
something other distribution may benefit from.

Would that be acceptable to add something like

  --have-working-poll=(yes|no)

to override the test?



2] it seems that build fails when submitting
  --with-fallbacks='some,terms,here' and when tic is not present in the
  system

I know it is not common situation and you usually have older version
of ncurses available but sometimes you need to build everything from
scratch.

Maintainer had to generate fallback.c with FALLBACK_LIST="" (not to
involve tic), build tinfo and tic to be able to build correct
fallback.c to continue with the build.

I think this can be considered as bug.

Furthermore, it would make sense to expose BUILD_TIC and BUILD_INFOCMP
to configure script as option which could help cross compilation in a
clean way...


I hope that these topics were not yet rejected or are not completely bogus.

Best regards,

Tomas Cech
