njoly 56695ef522 In is_number(), do not check strtod() result against HUGE_VAL which 
will result in a SIGFPE on non IEEE hardware. Instead, check the
provided buffer for "nan" string.

This make native build work again on alpha.

christos 8c8950af64 PR/39501: David Holland: Don't print the remainder of the line in the error 
context because it can confuse input parsing in warnings. A full explanation
is in the code.
 2008-09-09 21:47:34 +00:00
joerg f628ddd81d As dholland pointed out, don't leak memory if FS is resized multiple 
times.
 2008-08-26 20:25:19 +00:00
joerg 479fba4b1b Don't use strlen to check if the length is at larger than 1, check the 
first two chars directly.

Don't fail if FS is longer than 9 characters, but allocate a copy
dynamically and fail if that can't be done. Make inputFS static.

OK martin, bjs

small constant. Make the array of files dynamically allocated.

he 50d663aa6a Add support for multibyte charsets in the "tolower" and "toupper" awk 
functions.  Code contributed by Aleksey Cheusov in PR#36394, and slightly
tweaked for closer-to-KNF conventions by me.  Also slightly improved checks
of error returns.

apb 22d0439909 In setfval(), ensure that arithmetic never yields a negative zero 
result.  Now {echo | awk '{print -1 * 0}'} prints "0" instead of "-0".

preserving $0 in END block.

he a80853ef7a Make nawk retain the text from the last line of the input as well as 
the derived variables (fields & NF) under the END pattern.  This
implicitly complies with the SUSv2 specification at
  http://www.opengroup.org/onlinepubs/007908799/xcu/awk.html
which explicitly says that NF and NR must retain their values from
the last record seen.  Fixes PR#29659.
