Subject: build: Avoid length() awk function
X-Git-Tag: cygwin-3.4.0~462
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=332df71d3491f4f1024b14e2999cec4db13d4b39;p=newlib-cygwin.git

build: Avoid length() awk function

Some awk implementations such as old versions of mawk do not support the
length() function.  Use the return value of the POSIX split() function instead.
