Subject: Fix the program passed to AC_LANG_PROGRAM to be only the BODY of the main
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=91b538024a6fcecab80f422cb1fec52825faa44c;p=oota-llvm.git

Fix the program passed to AC_LANG_PROGRAM to be only the BODY of the main
function, not the whole main function. This problem resulted during
conversion of scripts to the new autoconf standard. The effect was that
the mmap_file test would fail and if it does there is currently an
#ifdef'd #error that causes compilation to fail. Bad, bad, bad.
