Wow... I'm really impressed, it was exactly this ! Single quotes instead of 
double quotes !  The reclass rules were written with a pipe to gawk, and I 
thought I would avoid escaping single quotes. I'll know better next time.

That solves only part of my problem, though: 
1. the boundaries are not dissolved with v.reclass, when they are with 
v.extract. I expect 79 new categories (vs the initial 45657...), does this 
mean I'm stuck with creating 79 vector maps with v.extract, that I'll have to 
merge one way or the other ? What way, BTW ?
2. I end up with this:

in a nutshell, I'm missing roughly 40% of my expected output map (luckily, not 
in the zone I should deal with). The pb may come from the fact that I have to 
process a coverage initially e00, that flattened several layers of polygons 
and non-boundary lines, plus some non-centroid point features. Top of it, the 
'new' v.in.ogr seems to dislike long (more than 10-12 characters) category 
names: I end up naturally with several columns sharing the same truncated 
name, that I have to edit to get the right value for the right field 
(something changed from my march/april version of 5.7...). The initial e00 is 
about 100Mb... Any idea ??

Thanks again...
