Ticket details:
The glob(3) function is provided by libmingwex.a. In addition to its
fundamentally POSIX.1-2008 compliant behaviour, it also supports several
MinGW.org specific features, and aims to support the GNU GLOB_BRACE feature.
Unfortunately, the MinGW.org implementation does not entirely conform to
behavioural expectations of GNU's own glibc implementation, (cf. this mailing
list thread); specifically:??
The brace-enclosed expression may not be adequately checked for
well-formedness, prior to expansion, and
An expression comprising only a single item is expanded anyway, and the
enclosing braces are discarded; this differs from expected GNU behaviour, which
does not result in expansion of expressions comprising fewer than two items.
Additionally, the usage of MinGW.org's glob(3) implementation within the MinGW
C runtime start-up code, when the GLOB_BRACE feature is enabled within the
_CRT_glob configuration variable, does not disable brace expansion for
expressions within quoted command arguments, as it should.
