I am trying to compile original gawk-2.13 source.  I created my own

config file which has BLKSIZE_MISSING, RANDOM_MISSING, and STDC_HEADERS.

Everything compiles without warnings except some complaints about

assigning const char *'s to char *'s, and the lack of a prototype for

popen() (I supplied the missing prototype, but why is it

missing anyway?).  When I tested the executable with some trivial stuff

it seems to work, but all the test programs that come with the gnu

distribution fail.  In particular, when awf formats text it comes out

without any control characters, and the rand() builtin always returns 0.

What am I missing?  Are there different warning levels with gcc?  If I

turn up the warning level will I be overwhelmed with pages of warnings?
