Hi,
i'm not shure but...
many programs that work perfectly before had started acting realy wired 
after installing :
 
Reading specs from c:/djgpp/lib/gcc-lib/djgpp/3.02/specs
Configured with: ../configure i586-pc-msdosdjgpp --prefix=/dev/env/DJDIR -
-disab
le-nls
Thread model: single
gcc version 3.0.2

The most strane gerror yet :
  Crt.ClrScr();
this function caused SVGA screen to bllink (like big black rectangle was 
drawn over screen, blinking was because this function is calling in loop 
that  draws every animation frame).
  So I removed all code od cCrt to get :
  void cCrt::ClrScr() { }
  and screen was still blinkgin.
But after removing line  Crt.ClrScr(); // that was in fact doing NOTHING 
everything was ok.
The code is quite simple, i'm shure that ther are no problems witn i.e. 
duplicated variables, etc. In code ther was only one call to Crt.ClrScr;

This is second situaction that code that was in fact NEVER used was 
causing erorrs in program. Another example was line :
  if (0) { .....  }
program crashed at exit with this line, and did not after removing it...
STRANGE :-/


I must check this exacly, but some errors realy looked like 
compilator/linker/etc fault... BTW. in some situactions gcc acted randomly 
- on same code, sometimes it crashed (!) during compilation, sometime 
everyting is ok...
