[Frama-c-discuss] [PATCH 2/4] test == is a GNU extension, use =

  • Subject: [Frama-c-discuss] [PATCH 2/4] test == is a GNU extension, use =
  • From: fr.inria.gforge.lists at coreland.ath.cx (fr.inria.gforge.lists at coreland.ath.cx)
  • Date: Sat, 27 Feb 2010 19:43:37 +0000
The next three patches correct the use of a GNU extension to 'test'.

POSIX specifies that "=" means equality, not "==". With the next
three patches applied, the configure process runs without error on
FreeBSD (also tested on Debian Linux to ensure that this didn't
break anything).
