After installing both cygwin and mingw I am able to build compiler with 
gprof support. I needed to pass libs path to the compiler

..\bin\i386-win32\make.exe clean all OPT="-gl -pg 
-FlC:\cygwin\lib;C:\programming\mingw\lib;C:\programming\mingw\lib\gcc\mingw32\3.4.5"

I have attached compiler gprof output of compiler itself. Using output I 
was able to find and improve(?) 3 functions I found in output.

What I can't understand why the biggest %time has the lowest seconds. E.g:
  %   cumulative   self              self     total          
 time   seconds   seconds    calls  Ts/call  Ts/call  name   
  5.11      0.36     0.36                             
CCLASSES_TFPHASHLIST_$__INTERNALFIND$LONGWORD$SHORTSTRING$LONGINT$$LONGINT
...
  0.14      7.05     0.01                             
fpc_shortstr_to_ansistr

As result I don't understand which functions must be reviewed at first. 
Have anybody tried that before?

Best regards,
Paul Ishenin.
