[PATCH v3 2/2] maint.mk: Replace grep with $(GREP) |
|
Date: |
Thu, 13 Dec 2018 18:34:53 +0300 |
A project that uses maint.mk can specify regular expressions that are
not supported in system grep. Autoconf can discover an alias for GNU
grep and set it in GREP but it takes no effect for maint.mk
The patch provides an ability to use GNU grep if it was discovered by
autoconf and by calling GNU grep we don't get the messages in syntax-check:
prohibit_diagnostic_without_format
grep: empty (sub)expression
grep: empty (sub)expression
grep: empty (sub)expression
grep: empty (sub)expression
grep: empty (sub)expression
grep: empty (sub)expression
