SynCommons.ExistsIniName endless loop (Delphi 2010 comp. warning)
I'm getting a bunch of compilation warnings inside SynCommons with Delphi 2010 and the latest nightly build (happened in older builds too). The most problematic warning happens during ANSICHARNOT01310 assignment: [DCC Warning] SynCommons.pas(13183): W1061 Narrowing given WideChar constant (#$00FF) to AnsiChar lost information.
Consequently ExistsIniName function goes into an endless loop while trying to check for "ORIGIN:" inside HTTP request header. The problem is actually inside GetNextLineBegin which stops advancing through request header once is hits 'z' because ANSICHARNOT01310 is defined as [#1..#9,#11..#12,#14..'y'].
This only happens when I clear all DCU files from the project and compile for the first time. However if I change anything inside SynCommons, which will recompile it again, it starting working perfectly and ANSICHARNOT01310 is now defined correctly as [#1..#9,#11..#12,#14..'˙'].
Any idea how to fix this without compiling twice?
Thanks!

Re: SynCommons.ExistsIniName endless loop (Delphi 2010 comp. warning)
The warnings disappear when I change something (like a blank space) in SynCommons and compile again. It works perfectly after that.
Seems like SynCommons depends on a precompiled unit which isn't there when the whole Synopse gets compiled for the first time. I'm not that familiar with the inner-workings of Delphi so I could be completely wrong.
However, I have tried to do that a couple of times today and it's always the same result:
- Clear all DCUs from project
- Compile whole project
- Run
- Test - doesn't work because it goes into an endless loop inside ExistsIniName
- Change a white space in SynCommons
- Compile again
- Run
- Test - works perfectly
