Hello Karim,

\r cannot deal with very long filenames:

? system(Str("echo Pi >",100!));
? 100!
%2 = 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
? \r 93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000
  ***   get_sep: argument too long (< 128 chars).

? read("93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000")
%3 = 3.1415926535897932384626433832795028842

The source code says
src/language/default.c

#ifdef MAXPATHLEN
#  define GET_SEP_SIZE MAXPATHLEN
#else
#  define GET_SEP_SIZE 128
#endif

but MAXPATHLEN is not defined.

Cheers,
Bill.

Fix in commit 43d88cb9. (We may assume that PARI stack is available, so
use it instead of a fixed static buffer.)

Thanks !
