build failure on fc20

[Ken McDonell <kenj@xxxxxxxxxxxxxxxx>]

My build just started failing on fc20 thusly ...

+ /usr/bin/gawk --posix '
...
            printf ("%%attr(%s,%s,%s) %s\n", $2, $3, $4, $6) >> f }
$1 == "l" { print "%attr(0777,root,root)", $3 >> f }'
gawk: cmd. line:133:     else if (import_sheet2pcp[$NF]) 
f="import_sheet2pcp_files.rpm";
gawk: cmd. line:133:                                       ^ yacc stack overflow

Anyone else seeing this?

Better still, any suggestions?

This https://bugzilla.redhat.com/show_bug.cgi?id=743343 suggests the problem 
may have been there for ages, we're just hitting it now because we have lots 
more packages ... 8^)

Can we change this code from 
if () ...
else if () ...
...

to
if () ...
if () ...
