FriCAS does not use sbcl threads, so if there is any use of
threads is due to internal sbcl code.

AFAICS the direct cause of this error is due to limitation
(you may call it a bug) in FriCAS: to compile category
you need access to compiled form of other categories,
sometimes even to the same category that you are trying
to compile. However, at this stage all categories should
have been compiled (in special mode which give somewhat incomplete
code, but enough for the current stage) and consequently compiled
form of INS should be available. So what may be wrong?
The first guess is incorrect information in databases.
Databases contain information about existing categories
and if a category is missing from database, then it
is not available for FriCAS. There could be some problem
with paths, but then you probably would get different
error message. First I would look if databases (in 'rf'
subdirectory of build tree look sane (they should have
the same content as during build on Linux)). The I
would check if .fasl files are available in target
tree
('C:/MinGW/msys/1.0/home/gvanuxem/fricas_build/target/i686-pc-mingw32/algebra').
To debug such problem I would start interpsys by hand,
starting it in the same directory and using the same
values of environment variables as during build. Then
I would try the offending ')compile' command by hand
looking why it failed.
