[tlbuild] zziplib package may need '--disable-mmap' option on MinGW

[Yung-Jang Lee]

Hi, all:

When  building  TL on MinGW , a test execution 'unzzip.exe'  in
'libs/zziplib' causes a segfault  with following messages:

------------------------------------------------------------------------------------------------------------

For testing, I download 'zziplib' source  from '
http://zziplib.sourceforge.net/download.html' ,compiling and testing,  and
also produce same segfault message when executing  'unzzip.exe'.

A blog

http://itsacleanmachine.blogspot.tw/2012/03/compiling-zziplib-with-mingw.html

say that :

  "Without --disable-mmap the library compiles fine, but causes a segfault
in some mmap function when accessing a zip file"

And I test this option ( '--disable-mmap' ) on my 'zziplib'-along package,
it pass the 'unzzip.exe' testing without  segfault .

May be 'zziplib' package need  to set  '--disable-mmap' as defult option on
MinGW ?

How can I test option  '--disable-mmap' of 'zziplib' on TL to see it's
effect ?


Regards.
