pkgsrc-2024Q3: emulators/wine flex error

[<tlaronde%kergis.com@localhost>]

Flex throws an error:

emulators/wine/work/wine-5.0.5/dlls/msxml3/xslpattern.l:150: negative
range in character class

The line number is not correct. The problem is line 149, because Flex
is apparently using signed char and such ranges:


NCNameStartChar ([A-Za-z_]|[\xc0-\xd6\xd8-\xf6\xf8-\xff])

NameCharEx      ([0-9]|[-._\xb7])

NCNameChar      ({NCNameStartChar}|{NameCharEx})


where hexa \xb7 and "more" are turned into negative char values.

I'm on:

NetBSD cauchy.polynum.local 10.99.12 NetBSD 10.99.12 (CAUCHY) #2: Thu Sep 26 16:02:35 CEST 2024  tlaronde@cauchy.polynum.local:/data/m/netbsd-10.99/sys/arch/amd64/compile/CAUCHY amd64

Where does the problem lie? The regex lib? How to force the use of
unsigned chars in character comparisons?
