You could check the C99 spec of course, which says gives (eg) strcmp as: int strcmp(const char *s1, const char *s2); rmk's rules of char: 1. use char for character strings and individual characters 2. use signed char if your data type relies upon negative char values 3. use unsigned char if your data type does not require negative char values, especially if it makes use of the positive values not present in the signed char range. IOW, use signed/unsigned when you need to explicitly state your requirements, but omit it for true strings and characters. -- Russell King Linux kernel2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core --- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.

[kbuild-devel] Fwd: RE: [BUG] 2.6.0: ARM won't build without CONFIG_CPU_FREQ_GOV_USERSPACE=y
There appears to be an issue with select vs choice statements; see the message below. Essentially, it appears a default selection in a choice statement takes precidence over an explicit select statement for one of the choice options. - Forwarded message from [EMAIL PROTECTED] - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED] Bcc: [EMAIL PROTECTED] Subject: RE: [BUG] 2.6.0: ARM won't build without CONFIG_CPU_FREQ_GOV_USERSPACE=y Date: Fri, 26 Dec 2003 10:57:54 +0100 Because of cpufreq_get() being necessary for SA1100 it is already special-handled for this architecture. A snippet from arch/arm/Kconfig: # CPUfreq on SA11x0 is special -- it _needs_ the userspace governor config CPU_FREQ_SA1100 bool depends on CPU_FREQ SA1100_LART default y select CPU_FREQ_DEFAULT_GOV_USERSPACE select CPU_FREQ_24_API if SYSCTL config CPU_FREQ_SA1110 bool depends on CPU_FREQ (SA1100_ASSABET || SA1100_CERF | SA1100_PT_SYSTEM3) default y select CPU_FREQ_DEFAULT_GOV_USERSPACE select CPU_FREQ_24_API if SYSCTL IMO this should cause the default governor to be forced to userspace, and the deprecated 2.4. API [including cpufreq_get()] to be activated as well. However, Kconfig thinks different: the default setting for CPU_FREQ_DEFAULT_GOV (see drivers/cpufreq/Kconfig) is PERFORMANCE, and this seems to take precedence over the select. IMHO this is a Kconfig bug -- can you notify the maintainer of this issue, please? Else we'd have to change drivers/cpufreq/Kconfig from default CPU_FREQ_DEFAULT_GOV_PERFORMANCE to default CPU_FREQ_DEFAULT_GOV_PERFORMANCE if !CPU_FREQ_SA1100 default CPU_FREQ_DEFAULT_GOV_USERSPACE if !CPU_FREQ_SA1100 or disable the selection for CPU_FREQ_SA1100 completely.
