[apluslist] A+ 4.20-2 compilation problem under IRIX

[Itzinger, Oskar]

Greetings, everyone...
 
I'd started to use 4.18/64-bit binary for IRIX last year and I'm very
much
pleased; I also compiled the source code for 4.20 successfully [albeit
after
getting rid of some error messages first].
 
Recently I'd downloaded the source for 4.20-2 [unfortunately, tar -xf
overwrote
my previous aplus-fsf-4.20 directory - please change that!]; anyway,
while I 
will post a full compilation report [including a configure warning and
some 
warnings about declared but not referenced variables] once I've
completely 
succeeded with 4.20-2, I'd run into the following errors (on my SGI FUEL
w/ 
IRIX 6.5.28 and MipsPro C/CC 7.4.3m):
 
=========
cc-3229 CC: ERROR File = ../MSTypes/MSFloatMatrix.H, Line = 30
  Specializing class "MSMatrixSTypePick<double>" requires "template<>"
syntax.
 
  class MSMatrixSTypePick<double>; 
        ^
1 error detected in the compilation of "AGIF.C".
=========
 
This was easy enough to fix - I just added "template <>" [without
quotes]
before the statement (BTW, when I'd compiled 4.20, I'd received many
more
errors of the very same type, so 4.20-2 thankfully fixed almost all of
them].
 
However, I'm lost with the following:
 
=========
cc-1324 CC: ERROR File = MSPrintDisclaimer.C, Line = 197
  More than one operator "-" matches the specified operands.

            The operand types are:  std::fpos<std::mbstate_t> - long.
      if ((mark2-mark1-len)>1)

                      ^
 
3 errors detected in the compilation of "MSPrintDisclaimer.C".
=========
 
My guess is that some parentheses are needed - but how should I set
them?
 
Your help is very much appreciated...
