I would like to expose some of my personal opinions in the hope they will be taken into consideration.
PellesC is a compiling suite created by Orinius Pelle a very smart swedish guy, who by himself wrote a bunch of software producing a very nice development environment targeted to MS world.
Pelle aim over all these years has been to stay as tight as possible to MS standards. The point was: whatever C project made for MS win (desktop or CE) should strightforfward compile on his suite.
Pelle also want not move to C++.
He offered the whole software free for any use, and in the meantime got some money selling sources to those who want them.
To free users was asked just to help development by testing code and reporting bugs.
While I don't know what would be the conditions if you buy sources (I mean if any support is included), for free use, even if donation was made, it should have been clear that the product was offered 'AS IS owned software'.
Pelle always programmed his suite as he liked, apparently accepting some suggestions and refusing many others. I said apparently because what was accepted in the 99% of cases was something present on MS suit.
His first long absence from the forum was when, very excited by the new IA64-AMD64 architecture, finally come back with a 64bits version.
Then maybe the decreasing interest in C projects from MS, maybe personal problems (his father had heart problems last year), maybe work and whatever else made him busy elsewhere.
Anyway this product is Pelle's child and he has the right to do with it whatever he wants, although he never let users with an outdated version (one that doesn't include all features to compile with last MS-WIN version).
Maybe he is working on Win8
Finally if you like PellesC suite you must take it as is.....
