[tex-live] Problems using Asymptote on Cygwin [TL2009]

[Angelo Graziosi]

On Cygwin (TL2009 for i386-cygwin), I have tried what suggested by 
user's manual: texmf/doc/asymptote/asymptote.pdf at page 82:

$ latex latexusage
$ asy latexusage

Here 'asy' seems to hang (40%-50% of CPU) and soon I find a 
'pdftex.exe.stackdump' file, which is not good...

Besides this, Asymptote creates an '.asy' directory in 'C:/Documents and 
Settings/user' instead that in /home/user, as it should be on Cygwin... 
It looks as if it is using USERPROFILE (a typical 'Windows native' 
environment variable) instead of HOME (which is used in an unix-like 
environment as Cygwin).

Are we sure that the Asymptote binaries shipped with TL2009 Cygwin 
binaries are not mixing Cygwin with Windows native (Mingw!?, perhaps!)?

Ciao,
Angelo.
