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);
^
exim_dbutil.c:568:1: note: use option -std=c99 or -std=gnu99 to compile your code
exim_dbutil.c:630:2: error: 'for' loop initial declarations are only allowed in C99 mode
for (int i = 1; i <= wait->count; i++)
^
exim_dbutil.c:642:6: error: 'for' loop initial declarations are only allowed in C99 mode
for (int j = 0; j < MESSAGE_ID_LENGTH; j++)
^
Fix by enforcing C99. This completes commit
2c692e81a844b30b4d3161dfd9897b3265bb9279 ("package/exim: fix host build")
to also fix target builds.
