Subject: lexer: Include <unistd.h> to ensure 'read' is consistently replaced.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=47f9412c378ef8e0bcce43566f72caa3b856580b;p=pspp

lexer: Include <unistd.h> to ensure 'read' is consistently replaced.

On some platforms, Gnulib #defines read to rpl_read.  The lexer uses
an unreleated function pointer member named 'read' in struct
lex_reader_class.  It doesn't really matter whether this name gets
replaced with rpl_read as long as it always happens consistently.
Adding "#include <unistd.h>" to lexer.h should ensure that.
