Configuring a lib containing special characters

[Marwan Badawi]

Hello all,

Sorry about the earlier empty messages I had some mailer problems.  But 
thanx to Bob Proulx, this one should finally get through (hopefully)...

I'm trying to tell my configure script to look for the SWIFT++ library, 
but whenever I use --with-SWIFT++-prefix=/path/to/SWIFT++ I get the 
following error: configure: error: invalid package name: SWIFT++-prefix/

/and part of the result of running  sh -x configure 
--with-SWIFT++-prefix=/udd/mbadawi/archivage/SWIFT/SWIFT++ gives the 
following:

++ expr x--with-SWIFT++-prefix=/udd/mbadawi/archivage/SWIFT/SWIFT++ : 
'x[^=]*=\(.*\)'
+ ac_optarg=/udd/mbadawi/archivage/SWIFT/SWIFT++
++ expr x--with-SWIFT++-prefix=/udd/mbadawi/archivage/SWIFT/SWIFT++ : 
'x-*with-\([^=]*\)'
+ ac_package=SWIFT++-prefix
+ expr xSWIFT++-prefix : 
'.*[^-_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]'
+ echo 'configure: error: invalid package name: SWIFT++-prefix'
configure: error: invalid package name: SWIFT++-prefix
+ exit 1
/
/Any idea on how to avoid this problem? (for now I just created a 
symlink without the ++ and it works  perfectly well)
Thanks,

Marwan
