Hello list,
I am new to the list so please bear with me for my first post.
background on my problem:
I am currently trying to compile gnupg for OpenCSW.
I have the latest version of gpg-error, libksba, gnu pth and libassuan.
I have compiled all with 64bit support. but when I try to compile gnupg
64bit I get an error that states libassuan using gnu pth is required to
build this software.
now for the relevant part for this list:
When I try to compile libassuan 64bit and force it to use gnu pth.
I get the error "FD_SETSIZE is larger than what GNU Pth can handle."
I tracked this down to the code below from /use/include/sys/select.h
--- code ---
#ifndef FD_SETSIZE
#ifdef _LP64
#define FD_SETSIZE 65536
#else
#define FD_SETSIZE 1024
#endif /* _LP64 */
#elif FD_SETSIZE > 1024 && !defined(_LP64)
#ifdef __PRAGMA_REDEFINE_EXTNAME
#pragma redefine_extname select select_large_fdset
#if !defined(__XOPEN_OR_POSIX) || defined(_XPG6) || defined(__EXTENSIONS__)
#pragma redefine_extname pselect pselect_large_fdset
#endif
#else /* __PRAGMA_REDEFINE_EXTNAME */
#define select select_large_fdset
#if !defined(__XOPEN_OR_POSIX) || defined(_XPG6) || defined(__EXTENSIONS__)
#define pselect pselect_large_fdset
#endif
#endif /* __PRAGMA_REDEFINE_EXTNAME */
#endif /* FD_SETSIZE */
--- code ---
My question is can I patch pth.h to allow fd_setsize of 65536 for 64bit
compiles without breaking gnu pth or opening up any vulnerabilities?
I have searched the bugs and the archives for this list to no avail. any
information you could give me would be greatly appreciated.

Thanks,
Mike
