[libvirt] [PATCH] Quieten build & ensure API build scripts exit with non-zero status

[Matthias Bolte]

2011/7/4 Daniel P. Berrange <berrange at redhat.com>:
> The current API build scripts will continue and exit with a zero
> status even if they find problems. This has been the cause of many
> build problems, or hidden build errors, in the past. Change the
> scripts so they always exit with a non-zero status for any problems
> they do not understand. Also turn off all debug output by default
> so they respect $(AM_V_GEN)

> * docs/Makefile.am: Use $(AM_V_GEN) for API/HTML scripts
> * docs/apibuild.py, python/generator.py: Exit with non-zero status
>  if problems are found. Also be silent, not outputting any debug
>  messages.
> * src/Makefile.am: Use $(AM_V_GEN) for ESX generator
> * python/Makefile.am: Tweak rule

Python has True/False, but you could also stick to 1/0 as the
generator code looks quite C-ish anyway :)

Why do you add the same code in the if and the else clause? You could
simplify this by adding it after the if/else clauses

Same comment about True/False.

ACK, as my comments are just about stylistic things.
