[patches] [PATCH] Fix alternative regex implementation

[Maxim Kuvyrkov <maxim@xxxxxxxxxxxxxxxx>]

Hello,

The attached obvious patch fixes alternative regex implementation to 
handle absence of wide char support.  This fixes building of EGLIBC in 
configuration

OPTION_POSIX_C_LANG_WIDE_CHAR = n
OPTION_POSIX_REGEXP = y
OPTION_POSIX_REGEXP_GLIBC = n

Committed as obvious.

Thanks,
