Submission from: (NULL) (213.54.77.26)


/configure does well in FreeBSD6-CURRENT.

When typing 'make' after a while I get:

Asking for the problem at R-devel I got this answer from Prof. Brian Ripley:

"R itself does not refer to __builtin_alloca.  That is something being mapped by
the FreeBSD headers, and it should be `builtin' using gcc.  (No version of
alloca is appearing as an import in error.o on Linux or Solaris using gcc.)  So
it looks like an inconsistency between your compiler and OS."

My gcc version is 3.4.2 [FreeBSD] 20040728.

There is no problem compiling R-2.0.1 and older versions on the same system.
