Hi all,
GCC 6.1 was relased late last month, and it was failing to build latest MonetDB, with the below 3 errors:
stream.c:2116:24: error: logical ‘or’ of equal expressions [-Werror=logical-op]
(errno == EAGAIN || errno == EWOULDBLOCK) && /* it was! */
^~
stream.c:2142:24: error: logical ‘or’ of equal expressions [-Werror=logical-op]
(errno == EAGAIN || errno == EWOULDBLOCK)
^~
mal_module.c: In function ‘getHelp’:
mal_module.c:455:3: error: this ‘for’ clause does not guard... [-Werror=misleading-indentation]
for(s= m->subscope[j]; s; s= s->peer)
^~~
mal_module.c:513:4: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘for’
m= m->sibling;
^
The first two appear to be because EAGAIN, EWOULDBLOCK have the same value on my machine (x86_64, Fedora 23 64bit). I don't know in what situation they would be different from each other, so I'm removing the check for EWOULDBLOCK and checking only for EAGAIN, as suggested by some on the Internet.
The third error is due to bad indentation. If we reduce indentation of mal_module.c:513 by two levels, that solves it.
