Description fcusack 2002-12-25 00:16:00 UTC 
This bit from gcc/configure.in:

if test "$prefix" != "/usr" && test "$prefix" != "/usr/local" ; then
  AC_DEFINE_UNQUOTED(PREFIX_INCLUDE_DIR, "$prefix/include")
fi

always includes $prefix/include.  (The condition can never
be false.)

Also, why is this always set?  This makes gcc
unbuildable in my environment (including in $prefix/include
requires linking against $prefix/lib, which I don't want).

Release:
3.2.1

Fix:
if test "$prefix" == "/usr" || test "$prefix" == "/usr/local" ; then
  :
else
  AC_DEFINE_UNQUOTED(PREFIX_INCLUDE_DIR, "$prefix/include")
fi

Hello,

visual verification of sources on gcc 3.3 branch and mainline (20030524) show that this problem is 
still present. Would it be possible for you to make a formal patch for this problem, attach it to the 
bug report, and send it to gcc-patches for review? Thanks,

Dara

Shouldn't be in WAITING...

We are want prefix to be inlcuded always with gcc since people install software them 
selves (not being root) so including $prefix/include is usefull for this.
Actually this condition can be false when $prefix is either /usr/local (which happens a lot) 
or /usr (happens when building the system compiler).
