        src/usr.bin/xlint/lint1: lex.c

Log Message:
lint: make parsing of GCC line directives stricter

The previous code accepted '# 123 "file.c" 23' as specifying a system
header, just because that number ends with '3'.  The original intention
was to compare the complete word, not its suffix.  Fix that.

No practical change since the only flags that are used by GCC are all
single-digit.
