[bash] $'\r': command not found

Error:
I got message below when I execute a bash script.
D:/asmbin/gnuasm: line 2: $'\r': command not found
D:/asmbin/gnuasm: line 4: $'\r': command not found

Solution:
It is caused by end of line is Windows style '\n\r'
Unix think the eol should be '\n'
Mac think the eol should be '\r'

The bash is unix environment, so we have to change '\n\r' to 'n'.
I use notepad++ as editor to fix the script.

[Webkit] fatal error LNK1106: invalid file or disk full

Problem:
Build Webkit on VS2008+Windows 7 32-bit, got the error message as title.
fatal error LNK1106: invalid file or disk full

Solve:
Install the VS2005 hot fix KB949009
https://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=18623

It is very weird for VS2008, perhaps I had installed VS 2005 before.

[Webkit] error LNK2019: unresolved external symbol localtime_s referenced in function localtimeOffset

When I build webkit with WinCE 6.0 SDK, I got the error message as title.
error LNK2019: unresolved external symbol localtime_s referenced in function localtimeOffset

To solve the problem, I remove the code in bold font below.

#if !defined(HAVE_LOCALTIME_R) && !defined(HAVE_LOCALTIME_S) && \
     defined(_MSC_VER) && defined(_CRT_INSECURE_DEPRECATE)
//#define HAVE_LOCALTIME_S 1
#endif


After that, I got the error message below.
error C2040: 'localtime' : 'tm *(const time_t *)' differs in levels of indirection from 'int ()'

To solve the problem, I add the code before where function localtime is called.
struct tm *__cdecl localtime(const time_t *t);

cr.~RefPtr();
    delete m_data;
