libjsw fails to emerge with the following error:

!!! ERROR: media-libs/libjsw-1.5.5 failed.
Call stack:
  ebuild.sh, line 1525:   Called dyn_compile
  ebuild.sh, line 928:   Called src_compile
  libjsw-1.5.5.ebuild, line 30:   Called die

The error can be resolved (however i'm not sure if its still the desired effect by changing line 135 from:

while(ISBLANK(reinterpret_cast<char>(*path)))

to:

while(ISBLANK((char)(*path)))

I'm not sure if this is a GCC or a libjsw error, however given the line

"invalid cast from type 'char' to type 'char'"

i'm guess gcc.  I tested compiling that file by hand (without compiler flags and other such things and found the same error message, so i'm pretty sure it isn't the ebuild or my settings that are causing the problem.

Tom
