Subject: [Patch] Fix configure test for __libc_stack_end
Date: Wed, 18 Jun 2003 11:18:08 +0200 [thread overview]
Message-ID: <uw54r2nyca7.fsf@saturn.math.uni-magdeburg.de> (raw)
The test for `guile_cv_have_libc_stack_end' does not work reliably
because the compiler can optimize away the use of the variable in the
test program. This happened to me on Solaris with the Sun Forte C
compiler.
Here is a patch.
