Browse Source 
Building with the Sourcery CodeBench ARM 2014.05 the build fails with this
error:

  >>> exim_dbmbuild utility built

  .../buildroot/output/host/bin/arm-none-linux-gnueabi-gcc -DEXIM_DUMPDB exim_dbutil.c
  exim_dbutil.c: In function 'main':
  exim_dbutil.c:568:1: error: 'for' loop initial declarations are only allowed in C99 mode
   for (uschar * key = dbfn_scan(dbm, TRUE, &cursor);

Fix by enforcing C99. This completes commit
2c692e81a8 ("package/exim: fix host build")
to also fix target builds.
